Thoughts on Brunton Stalker 3.4L V6

[b10bt]

Would Brunton owners and others who have driven a Stalker (non-supercharged version) care to give their driving impressions and thoughts regarding Stalkers? I am interested in a Stalker that is for sale in my area and am trying to do my research. The main source of info has been the stalker website. Unfortunately there aren't traditional automotive car reviews or test drives of our beloved seven car kits.

 

How is maintenance on Stalkers? Comparisons to say a Deman SR27 other car-based engines would be welcome.

 

Thanks,

Victor

While I have to say that I like the lines of the modern Caterhams (the skinny ones) the best (well, maybe except for the Dax!)...I know first hand that the Stalker is CRAZY FAST and a good value.

 

And the fact that the builder of one of the most refined bike engined Locosts in the US (Jeff U) has said that if he had to do it all over again, he'd build an S2000 powered Stalker should speak volumes.

And speaking of Stalkers, will one of those engines from a Buick GNX fit?

[slngsht]

The GNX... that was an awesome car in the 80's...

 

Looking back though, that engine only made about 270 hp and 360 ft.lbs. of torque (well "only" by today's standards, back then, it was :willy: ), and with the turbo and related plumbing, is actually heavier than a LS1. Although, they can make crazy power if you gotz the $

[slngsht]

Victor, what kind of feedback are you looking for? for a track car, weekend car, etc...

 

Stalkers have performed VERY well at the track. Have a look at the results of the run 'n' gun for a sample. They're also fairly roomy, and with a chevy drivetrain, cheap and reliable.

One thing you might consider if you're interested in autocross is that 7's over 2L displacement are E-Modified, rather than D-Modified... so you're doing battle with some pretty serious purpose built race cars. Not that D-mod is all that different... but at least the motors are smaller! It's just something to consider if you're in to that sort of thing- particulary when you consider that there are a lot of sub 2L 4-bangers out there that can produce comparable power to the 60 degree V6 for less weight... But I admit that it's tough to match the V6's torqy-ness with a high strung 4-cylinder.

 

If you're not concerned about your autocross class, the 3.4 displacement issue may be a moot point.

 

But I have never personally been behind the wheel of a Brunton, so take that for what it's worth.

Tnanks for the replies everyone. I live in Vancouver, Canada (pacific northwest). Call me crazy but I intend to buy a seven to drive daily to and from work. It will not be to race other cars. I might take it out for track days and HPDE events but will not race in SCCA, Solo II or other type events. That is why the idea of a car engine for a daily driver appeals to me. In British Columbia Canada, we face an unusual challenge in obtaining a sevenesque car. Canada does not allow us to import a whole kit car from anywhere in the world. You must bring it in in parts and bits and pieces. However, I can buy a seven which has already been titled as a 1960's Lotus Seven for example. It is rather complicated.

 

In BC, if you build a car from parts, it is classified as a UBILD (you build. Get it?) vehicle. An independent safety inspection will scrutinize items like the upper\lower control arms, axle, brakes, pedal assembly, steering rack and other such items to make sure you have not compromised their integrity for safety reasons. An unaccomodating inspector can completely derail your attempts to register your car. There are other issues such as functional windshield wipers, demister (cigarette lighter powered fan qualifies), bumpers, etc. It is not a simply open and shut case. Therefore, buying an already assembled car which has been previously registered in the province is very attractive as I don't have to pass any inspection to insure the car for the road.

 

I would outfit any seven I buy with a canvas top and side doors since the weather here is rainy. The one I am looking at has a 4.11 rear end final drive with a limited slip differential. The Brunton Stalker appeals to me because its inexpensive, parts are accesible and plentiful and seem to be well regarded in the 7-community especially after their showing at Run and Gun and Tail of the Dragon. In an ideal world, I would also love a Deman SR27 but I believe it is outside my price range. Ditto the Hayabusa Deman. Genuine Caterhams are available from Vancouver island but they start at $55,000 and go up from there.

 

Is driving a Stalker a very unrefined driving experience? How does it compare in refinement compared to other makes?

 

Al, your comment about what Jeff U said is a very strong endorsement. I am surprised. That must be due to the chassis design of the Stalker, it's rigidity, suspension pickup points and so forth. The engine being a GM standard unit, is unlikely to be a star here other than providing gobs of torque. It doesn't even use an IRS. Very likely the Stalker is an example of where the whole is greater than the sum of its parts. None of the parts are particularly exotic, yet the whole seems to work exceedingly well.

 

My other car is a 1990 BMW Alpina B10 BiTurbo. If any of you are BMW fans, there way a writeup on this car in Bimmer Oct 2007 and a smaller writeup in the current issue of Roundel. It has about a 10.2 lbs/HP ratio. Engine produces 360 HP/ 384 TQ. Photos here: http://www.bimmernut.com/forum/showthread.php?t=35965

This is a funny question in the context of a Seven....but if you are looking fore a refined sports car driving experience you may want to consider a Porsche

 

Joke aside...I guess for most of us being a little raw and unrefined is one of the desired properties of a Seven.

 

In terms of ride quality (if that is what you mean) my observation is that rather depends on the individual setup than on the Brand/Type.

No, no. I meant driving the Stalker compared to a Caterham say SV R300, SV Roadsport, Westfield Miata, Birkin, W2K - other seven or sevenesque cars. I have experience with 911, 911 Turbos, Viper, Corvettes, Murcielagos and Alpinas... Driving a Seven is appealing because it is very unlike the cars I've listed above.

 

There is also something very appealing about a back-to-basics car without power windows, er, windows, a carburetor with a lovely induction sound and without a ton of electronic gadgets. The only concession I will add to my 7 is a GPS unit like a Garmin and a cellphone charger for safety.

[xromad]

Yes!

 

A number of general observations.... and a Disclaimer: I own chassis #20 with a 3.4

 

1. Very nice torque, very smooth, lots of power, not finicky at all. Push the go pedal soft and cruise all day long...or...Push the go pedal hard and hold on tight....

2. Very good suspension, quite smooth. Stiff, but not harsh.

3. Excellent engineering on the suspension. The geometry is excellent and very very strong.

4. Excellent quality control on the frame. Bolt holes actually line up.... Parts actually fit... Paradise!

 

The Stalker owners I know are all excellent people who have put a lot of love and craftsmanship in thier cars... But, as with any kit, once it leaves the factory, the owner can do all kinds of nasty things to it. Make sure nothing was drastically changed by the current owner and you will be rewarded with an excellent car. If in doubt, call Dennis he will definately give you a good assessment.

 

On the question:

 

Is driving a Stalker a very unrefined driving experience? How does it compare in refinement compared to other makes?

 

Yes....But.....

It depends on how you choose to define "refined driving experience". If you are talking about absolute precision handling and go-kart like reaction. The seven is almost unequaled in the world. If you are talking about a sip of Cognac from the wet bar while James, the Chauffeur, takes you through London traffic to meet your Mistress, I suggest a Rolls Royce Silver Wraith, or perhaps if your pockets are quite deep a Maybach would be suitable. :jester:

 

and no.....

1. The torquey motor gives it a very refined feel. You don't have to flog it to drive it. Power everywhere and easy to use.

2. The shifter/tranny gives it a very refined feel. I have had many people comment on the feel of my "Brunton Lightning-shifter".

3. The ride - as stated earlier is stiff but not harsh. I think it feels very taught and refined.... Some would think otherwise....

4. Sheet-metal interior and fiberglass bucket seats.... Most would call these raw, I call them functional. To this point, I have a "Real Truck" and a "Fake Truck" in my garage. The fake truck is stronger, faster, better gas mileage, smooter, and better in just about every way you can measure, but it is still a "Fake Truck". The easy way to tell the difference is that I wash the INSIDE of the real truck with a garden hose...... I LIKE the sheet-metal interior.

I was going to put this pic over on the BEC section to show the progress but then ran across this post. Please excuse the "Rat rod" appearance, its being built outside and trying out different primers the metal sheets have to be shot on both sides to prevent rusting. The engine is a Buick 3.8lt Regal,non-turbo, with a.....wait for it........ automatic! The torgue off the bottom is amazing. I have an avi clip, its power braking around 1000rpm with the wheel spinning and with Cherry Bombs its quiet. The hoops are for the hard top and gull-wing doors, the styling might not be for everyone but every 7 fits their owners, no two a like. My car feels frantic all the time because of the R1 engine, but this one is the cruiser; heater, radio, NAV? planned. All parts are AutoZone friendly. Dad was so impressed with the Stalkers at the 50th meet, he decide to build his own but he wanted an everyday,all weather car. Victor, they are an impressive sum of parts and more drivable daily compared to a BEC. My personal opinion is the Westfield/Caterhams have a better fit-n-finish but if you put some personal time in like you did on your Alpina, beautiful car by the way, it should surpass them. I wouldn't be afraid to get a Stalker.

When I was 7 shopping, I tried everything on the market. The Stalker was the clear choice for my needs. The engineering is well done, the fiberglass parts are top notch. The drivetrain is simple, reliable and way powerful. Sounds good too. The 3.4 is more than you'll ever really need on the street and plenty quick on the track. I've even taken to starting autox in 3rd gear, spinning the 10 inch slicks and not bothering with any shifting on the whole course.

 

It is simply the best value out there for the performance. Getting to know Dennis Brunton is an extra bonus.

Oh, and you mentioned the Stalker website, but did you know there is a picture gallery at the link above? Mine is chassis #38 on the second page. There are some neat cars there.

 

There is also an owner's-only forum that you will join if you buy one. There are great folks there that can help with anything you can come up with.

[b10bt]

Thank you for all your responses. I am trying very hard to get this car as I have explained above, getting a kit car in BC is not a simple matter. Will keep you updated as to what happens.

 

Andrew7, thanks for your encouragement. Do share the photos once yours is complete!

 

zbxb, you have a PM.

I also had many Porsches, and more than my share of exotic cars. For many years I had the wants for a seven type car, but never made the time to dig into them. The only good American powered powered cars I had was a AC Cobra & a Griffith. About 4 months ago I picked up a Birkin, and have enjoyed it. The little 2.0 Zetec pulls well at all RPM. Not wildly quick, but very nice. As I had read about, it is loads of fun below 100MPH. Untill I got mine I didn't understand how it could be fun at low speeds. It is a riot! You can push it and toss it around and still be at below go to jail speeds. With most of the others fast started at 150 MPH. I would think any type of 7 will deliver the same fun.

Enjoy

Victor,

 

Adding a plug for remote mounted GPS and Cell phone is certainly no problem. I use a GPS unit when we travel in the Stalker. It works great as you can kind of see in this photo taken at the 7-7-7 event this Summer.

The only thing that I feel you might do with the Stalker that you are looking at is to eventually change out the 4.11 rear differential to a 3.43 set of gears. I think it will be much more favorable for cruising. That is the set up that I have as do most of the other Stalker owners. You can easily take off in second gear even with the higher final drive ratio plus have plenty of comfortable power and torque in 5th gear.

 

Other Se7en owners have driven my car and the first thing that comes out of their mouth is "Geeze, this car has gobs of torque and is crazy fast...I only have a 2.8L, 60° S-10 pickup truck motor in mine. It has been warmed up slightly. A stock 3.4L from the Camero or Firebird is plenty fast and extremely reliable as others have indicated in previous post.

Thanks jbanker. I have used your pic as my desktop wallpaper to keep me inspired!!

 

Current owner tells me the 4.11 is so low, he starts in 3rd gear. So yes, 4.11 is a bit too low to be useful. However, the important thing is for me to get the car first and tinker later! I am so conflicted between trying to be financially responsible and wanting a car of my dreams...

I don't have a Stalker, but my motor is similarly torque happy, and I had 4.11 on there. I switched it to 3.42. Before I switched though, I was at an Autox school, and one of the instructors drove my car, with me riding shutgun. He drove several runs, and in one of them, he accidentally started in 3rd, and shifted to 4th, rather than 1st/2nd. After the run he said "didn't the car sound different that time?". I said yeah, that's b/c you ran in 3rd and 4th. He couldn't even tell the difference :lol:

 

With 4.11 1st gear was pretty useless, although it was nice to climb a steep hill by just letting out the clutch.

[b10bt]

Slngsht, your comment about the 4.11 is duly noted. Thanks a lot!

[lowflyer]

I've had my 3.4 Stalker for about 2 years now and love it.

 

More power than most people would ever use. Something that isn't well known about the Stalker is that, while it uses the 5 speed out of an S10 truck, most Stalker owners never use 1st gear.

 

Actually "almost never" is more accurate in my case. I do use 1st to get it up the trailer ramps at low speed, and occasionally use 1st just to make sure that it's still there.

 

In second, the car will pull smoothly away from a stop, or light up the rear tires just about all the way to 50 mph or so, when you shift into 3rd.

 

Mine is equipped with a 3.42 rear end and with the 5th gear overdrive it turns about 3000 at 80-85 mph.

 

Refind? not a bit! I wouldn't have it any other way.

 

The real difference between the Stalker and many of the other Lotus clones is that the Stalker will allow us "full bodied Americans" to enjoy driving a go kart on steroids, while most of the European based versions seem to better suit smaller folks. I'm about 6'2', 250 lbs and have an size 11 shoe. I doubt that I would fit into most of the others out there.

[SuperStalker44]

See my post in cars for sale. My Super Stalker is for sale and if I don't sell it in FL by Feb, I'll be moving it to Seattle. Take a look.
