Turbos on a Seven

[MoPho]

:banghead: You don't need that much torque in a 1200lb car!

 

Why stop at a merely one turbo? Why not add two? And might as well add a twin clutch automatic, AWD, electronic diffs, ABS, big Brembos and some 19" wheels while your at it. You know one can't let any of dem Nissan GTR's pass after all!!! :driving:

 

 

 

You win! I guess after 13k miles I know nothing about how these cars drive :seeya:

If I may, I'd like to add a couple of cents (sense?) to this spirited discussion: fast through the corners, straightaway drag race to the next corner, at the end it's what the timer registers....lap times are lap times, whether you're timing against yourself or others in your session. If you're a pro or competitive racer, of course you want to post the fastest (best?) time. All in all, enjoy, learn, and improve your times in stages, little by little. None of us want to die in our Sevens to prove a point. I'm totally happy with the TWM/Pectel ITB setup on my Zetec. I'm not a track racer, but my Cat has all the power I need for a head-turning street machine and don't need anymore. The 3 7's I've had at different times in my lifetime have given me an enormous amount of satisfaction and pleasure, but still really admire those of you that want to squeeze all you can out of the car, if for nothing more than the ability to engineer and produce results and to satisfy your interests and curiousity,i.e. just because you can. You're blessed!

Well I must say this ..... If you just like to drive a 7 for fun on a beautiful winding road just do it as often as you can.... Life is short. I ain't worth arguing over when you can be driving.

If you are built like Westtex, John M and myself and you would prefer to blow by a GT2/3 vs waiting for a gracious point by (the GT 2/3's I race with be pointing their fingers at you when they blow by... )

Then more horsepower to ya.

7's are amazing cars,

7's with more HP are more fun (IMO)

7's with ass loads of power under boost or V8 are 100% orgasmic !

BUT... They are not for everyone.

Regardless 7's are just cool to drive .... so go drive and keep smiling

YOU dont need that much TQ in a Caterham , that is all you had to say , that I can understand and respect , It isnt for everyone that I understand and respect

For those that are curious about a Turbo and more TQ/HP I am interested in doing one

I did, before you showed up and started talking about horsepower

 

 

Yes, but the turbo motor tends to put the torque peaks down low which on a low weight car, especially one with little weight on the back of the car, isn't necessarily ideal.

 

[westy turbo]

I know its been sais thousands of times....7 is light,turbo makes it more light....

if the turbo is specked right,in addition with a AVCR,then you choose how you wanna shoot with your weapon....if used correctly,can even take down bigger giants that used to as an N/A engine.....

Its personal choice.

That's funny and it seems to show a commonality of opinion of GT2/GT3 owners. A couple of years ago, my buddy and I were at Roebling Road with our 2007 Z06's for a track day. The Porsche club from Nashville, TN rolls in with some awesome trucks, trailers and of course, cars. I was amazed at the quality of their gear (read that jealous). We went out for the first 30 minute session. We were lined 2 x 2 on the false grid so I was beside one of the GT2 cars. I motioned a thumbs up to the driver on his car only to be looked at as if I was trailer trash. Ok, whatever. Well gloves were off after that, and my buddy and I lapped the GT2's and GT3's easily, several we lapped twice, and one I lapped three times in 25 minutes of running. Second session we were even more brutal. Then we broke for lunch. Ron and I went over to see their rigs and they refused to talk to us, pretended like we didn't exist. A bunch of rich guys with beautiful capable cars who can't drive worth a crap. You can't buy class.

That is funny - I can relate to that. The NJMP Sevens track day in June 2011 was like that. We crawled over the asses of 911s, Corvettes, Cocksters, a Caddy CTS-V, Camaro, etc . None of them wanted to give us point bys until middle of the day when they realized they were better off to let us go. Definitely some bruised egos especially when one Corvette driver found out Kitcat was running a Crossflow :rofl:

[7evin]

@ Klasik & Croc

These are some of my favorite Days.

I have had them look at my car and ask what class I was running ? I tell them their class and they laugh and say I doubt it... I always giggle to myself.

I follow them for several with my front wing tucked up under their tail (just to make them nervous) then blast by them smiling and waving.

I always go by and visit with them afterwards and brag on how great their car looks on the track and how I liked the lines they were carrying through a particular corner.

At that point they will either be a real man or continue being a snob.

Most of the time they are cool and realize they completely underestimated what they were looking at.

On the other hand I have seen the GT 2/3's driven well and you will play hell to catch them.

I pressumed that crossflow has 1.6/1.8 pinto block and has a power between 140 to 160?

So, bring on that 370hp Ford focus TURBO and see what it can do (as I suggested before). If he beats it, he'll make more money turbocharging some of your ZETEC.

I think it was the 135 FWHP version. If you bring on 300+ hp version turbo or supercharged, I would still love to see the Corvette (or Porsche or whatever) driver's face. He would not know what hit him! :rofl:

[Kitcat]

Well, I have the chassis dyno to prove the mighty X-flow was "unleashing" 95 hp at that particular gun fight:). And 93 lbs of torque. Too bad Mr Vette:). Our se7en's pretty much ruled.

 

But if I have learned anything in my countless trackdays, it's never underestimate anyone, and that includes Ford Focuses. Other than our group's fun at NJMP last year, my fav trackday occurred when all my cars were laid up and I was forced to take my little Honda Accord, auto, 4 cyl to a long planned event. The other drivers were smirkin like crazy. But then it started to sprinkle and the little Honda was as fast as anyone. Many egos were dented:).

I'm going to have to get out on the track in my seven. I've done a handful of Porsche club days back when I owned an 81' and later an 84' Carrera. I was one of the slower guys due to equipment, limited skills and concern over damaging myself or the car.

 

I wonder if the inherent lightness of the seven will mean that I mentally adjust to much higher corner speeds as my brain adjusted to the idea of dramatically less momentum being thrown around.

I will take care your anemic 95hp with this turbo used for drone & stihl chainsaw competition---> so next time u beat the Aventador.

That little turbo is just to cool.....could put one on each exhaust tube and then you would have a quad turbo (on a four cylinder 1800cc engine) that might give enough boost to a manifold that would maybe make a difference and improve HP.......:smilielol5:

I could see it now in the pits when someone spots a setup with four or more of those the head scratching that would take place.....:smilielol5:

 

Might get more boost from the Vienna Sausage's......:smilielol5:

[danilo]

Sadly Cross flows.. really.. don't like Boost.

Seems there is a genuine lack of steel (iron?) between the bores.

Fairly common knowledge 30+ years ago though.

If we forget history.. we get to repeat it :-)

[thegoat]

Do I really need to know what a car is "about" to make statements about adding a Turbo or more performance, I have drove several Caterhams/Berkins and I see where there appeal is and like I said with 180-190HP to the wheels with my built engines and I still feel they can handle more power

 

I have asked Caterham/Berkin owners with 170-180 hp to the wheels if they felt the Caterham/Berkin would handle another 75-125 HP to the wheels and they have all said yes and with out loosing its handeling ability , you can even buy 250+ NA Caterham engines do they cause adverse effects in the way the car goes around the track ? Not that I have seen

 

Turbo isnt for everyone and I know that, I mentioned Focus because thats what I do most ( Focus-Power ) and where I cut me teeth on the Zetec in 1999

I have one of the newer 2.0L Duratec Birkins that put out about 165rwhp. I only run 205s at the rear and am fully to the floor with my accelerator all the time at the track. The car is wicked fast as is, but it could certainly handle more power, esp. on the straights where there isn't enough hp to push through the aero block that we start to hit around 110mph. Put some wider, stickier tires on this car and I would be stupid not to ask for more power.

 

I am a little concerned about adding weight (sitting at 1197 pounds right now), but I am thinking that the power will make up for it.

 

However, I have been looking at the supercharger that Dick Brink has. I have an STi as my non-sunny driver and previously had a SCd Exige. I think I prefer the linear power of the Exige over the turbo'd STi. I will admit that my STi has the stupid stock tune on it though.

 

But to the question of whether these cars can handle more power - yes, without a doubt.

[Guest Terry]

I would totally agree that the Caterham take way more power, I'm not sure about the others, however up to a certain number the amount of power is not the issue the issue is the power delivery. Our Hayabusa Caterham produces 394 BHP with a totally linear power curve, however it only produces 160 gt lb torque, it is blindingly fast, real easy to drive and is going get more power. Keep away from high torque engines.

[WestTexasS2K]

400 hp is good fun and you can use most of it most of the time. I prefer more torque. Lower torque tends to keep things from getting torn up. IMO you cant have enough torque. My new engine is being built for wide flat torque curve. I'm not going to concern myself to much with hp on this one. It should be a respectful 320-350 range NA.
