That is cool!

Rocker assy don't look strong enough it looks like they will bend under a load.

I have always loved that body style. I have been trying to by one of three 190 coupes sitting in the same place for last 30 years.

congrats that looks like a great deal.

I prefer the Blackjack Zero. It is driven by the front wheels making it Handel very good. It will do close to 1lat G. Kit isn't too expensive. It will take Moto Guzzi or VW engine.

Talked with Richard from TTS engineering in the UK he is distributor for Rotrex in the UK and builds some nice kits mostly for bikes but he does alot with Hondas too. He has done some experimenting with CR on motors running the Rotrex and says that changing from 9.5.1 to 11.5:1 will pick us up at least 100 hp. He has proven it a number of times on the S2000, Hayabusa and Triumph motorcycles he builds. So I guess that is going to be our next step is to put some pistons in. Maybe do some head porting and we should be in the 550 -575 range. That should be enough to get us there.

Hey Busa I am not sure if 7evin will change to a turbo since everything is built and packaged around the supercharger, but my new car will be turbo charged. So I may need to pick your brain a little on turbo sizing. I was planning a GT30 dual bearing unit but they come in different trims and I am not sure I understand the a/r for the compressor and turbine sizing I will have to get educated on that. I will be running a fully built motor as well so it should be good for about 700hp range. I think I will be happy with 450 range for the most part that is what is nice about the turbo just boost it alittle more if you need some more power.

Busanostra We are running the largest they make 38-91 not even on the market yet. I agree turbo makes more power. We lowered compression ratio to much also so we will bump up compression and spin it a little harder to get the power. We need a lower gear ratio too that we can get by going with 15" wheels to change final drive ratio.

He is probably a Swiss watch maker!

Jlumba81 We have -8an for supply side new pump seems to be working great.

He has a new pump on there now to handle the requirments. Remember we are running on e85 so you need to flow 40% more fuel than gasoline. I have a few pictures on my phone but I will need to download to my computer so that I can post them. I havent been at home much for the last week.

I thought I would type up a quite note of what 7evin did at the Texas Mile event. He posted it under the Ultralite under construction, but most folks who dont care about the Ultralite might not have looked in there. We went down to Goliad Texas to run the Texas Mile on Oct 23 & 24. This event is a standing mile so its like a drag strip run that doesnt end for a mile. We went with the goal of doing 180 mph which is pretty fast in a LSIS type vehicle. 7evin is running his new engine and from the previous dyno session we were only able to get 338 rwhp out of the car. We just were not able to build the boost we wanted. So a call was made to Rotrex and they sent us a prototype unit that isnt on the market yet. It is their newest baddest unit they make. It is several sizes larger than the unit we were running. 7evin was a week away from having to go Texas when we found this problem out so we were agianst the wall in getting the new supercharger. It came down to the wire. If it had been anyone other than 7evin and his wife Michelle it might have not gotten done. He wanted the supercharger to ship on Monday overnight and arrive on Tues. It didnt happen. The supercharger was having to machined from billet since the new molds were not done this took alot of time of course which delay the shipping until Wens 2 days before the event. They finally get confirmation that it had shipped to GA. Problem being they were no longer in GA they were headed to Dallas Tx and were going to have it shipped there where it was going to be changed out and retuned. So Michelle had to get in touch with UPS and track down the location and have it diverted to Dallas for delivery Thursday morning. Believe it or not it showed up Thursday morning. (If that were me I would have given up and gone home! ) He got the supercharger changed out at Jotech shop. Which is really nice of Kenny Tran he usually doesnt let customers work on their cars in his shop. Supercharger is changed out and Kenny starts on the new tune. The new supercharger is now making good boost so much so that the fuel pump cant keep up in the upper rpm range. When the car got to 8900rpm it would start to loose fuel pressure. We really need to go to 10k rpm to hit the shift points and to carry boost levels thru gear changes. So it is 8:30 Thursday night and they have no place to get parts and they really need to leave Dallas that night to get it to Goliad and set up for the race. So they had to leave the redline at 8900 where the car made 410rwhp. Still short of the 500rwhp we were shooting for. 7evin get setup for the race I arrived late on Friday. Keith Cox who helped us get to this point flys in to assist us for the weekend. He is incredible knowledgeable and was very instrumental in getting the car together. First run Sat morning was done about 10 am and was done just likely we normally run the car on the track. Front and rear wing were left on we put the upper air foils at the lowest angle of attack removed the front fenders and headlight. We did 143 mph the first run. We came back to the pits removed the upper air elements in both front and rear wings. Taped up the front grill to limit air movement into the engine compartment. Second run we did 162 mph. (those wings created alot of drag) The car was very stable at 162 with just the bottom elements. Third run we removed the rear wing completely and taped the grill up a little more and ran 167.2 mph. At this time we were fighting very stiff winds about 20 mph that were hitting us on the right side of the car. That was all the runs we could get done on Saturday. Sunday we decided to break out the "secret weapon". Keith had made a nose cone that slipped on and extended the front of the car about 2ft and sloped the nose all the way to the ground. We installed skinny drag tires on the front and slicks on the back for more speed out of the hole. The first run we did 167.3 mph but 7evin noticed the fuel pressure dropped at the end of the run and he had to get out of the throttle. When he returned back we had fuel running out of the rear pan. We began to investigate and found that the seal had gone out on the fuel pump. 7evin had a rebuild kit handy so we rebuilt the fuel pump and found that the bearing had also gone out. This allowed the rotor to scuff the wall on the pump. We got the pump rebuilt had to redo it several times before we could get it to stop leaking. Finally no leaks but still low fuel pressure. So off the pump comes again still nothing can be found. So we scrounge up a Pump from another team adapt it to work in the car and still no fuel pressure. Upon further investigation we found the jam nut had vibrated off the fuel pressure regulator and the stem had backed out letting the fuel bypass. So we fixed that and now we have 60 psi again. We make another run and we still have problems with the low fuel pressure. We decided to stack the pumps in series and it seemed to work with keeping fuel pressure up but we were not able to gain in speed. That was our last run for the weekend. We are going to try again next spring. Hopefully we can have a few more test sessions under it some stuff sorted out by then. 7evin put a fuel pump on there that is massive and lights on the city block dim when it turns on but it pumps massive amounts of fuel. Some more tuning were we can get our rpms up and some gearing changes I think we can reach our 180 mph goal.

I have been wanting one of those for awhile. I will have to keep dreaming for a little while longer. That is going to be so sweet. I would have choosen the helical over the straight cuts too. I have to admit I am a little envious.

I very seriously doubt you are just spinning tires in the just the 8-9k rpm range. You are more likely to experience this problem when Vtec kicks in. What gear are you in when it happens?. I can see spinning wheels in 1st 2nd and 3rd gear ,but 4th isnt likely unless you have very bad tires. It should be very obvious when tire spin happens. The back end will usually move sideways left or right. It sounds like you steering is just getting light and unstable so it gets a little scary at highway speeds 70-90mph range. In all you alignment specs I see nothing about caster in there. Caster gives the car stability at speed. The less caster you have the lighter and more sensitive your steering is going to be. The more caster you have gives you more stabilty and will also increase steering effort at low speed and the steering effort will get easier as you pick up speed. For a street car I like 5.5-6 degress of caster. You can take your hand of the steering wheel and it will track very straight. I think you can use a little more rake in the car as well. The specs you gave you have 10 mm of rake not sure if that is with you in or out of the car. If you set that up with out being in the car then you may be dropping the rear to much while you are in it giving the car a nose up attitude and this will cause some problems in stability. If the car only gets very light under acceleration which is expected, but if it is to a point you feel insecure in the cars predictabilty. You might want to go to a stiffer rear spring to keep the back from squating so much under acceleration. In return this will keep more weight on the front tires and keeping the car planted. Aero work isnt really going to affect your car handleing and performance until you get up to 110 mph or so. At highway speeds I dont think you will notice much of a difference. I dont know what rear end you have is it a straight axle or IRS? If it is an IRS you might be getting bump steer when the suspension moves it changes the tow on the tires making a handful to drive. Tires are very important on a light 7 type vehicle. The Mickey Thompson tires are more drag oriented tires. I know that it says that it is made for drag racing and street use. I think you will find the the sidewall are very flexible on that tire. They use are pressure to support the sidewalls. On a seven you run below 20 psi which can give you alot of side to side movement as the car walks over the tread when underinflated in a soft side wall tire. I would stick with tires that are known performers on sevens. That has been hashed out here several times before. There are many brands and depending on the use and weather conditions you drive in. Toyo RA1 or R888 are good max performance tires. Michelin Pilotsport 2 are a very good street/ trackday and are excellent in the rain. ( Most people dont drive in the rain.) There are dozens of brands and models to choose from. Hope you find a solution to the problem but I think alot of money on aero work isnt going to give you a good return on your money.

We made 20lbs of boost with the new supercharger. This gave us about 90hp gain over the other supercharger. We have run out fuel pump capacity though and cant pull to 9500, we start to loose fuel pressure at 8900. The tuner thinks we have another 30hp or more in there but we need to upgrade pump. Those 4x1000 cc injectors will move alot of E85 more than the fuel pump can supply. So we are going to have to run the Texas Mile short on hp. Kevin and his family/friends have busted their humps to get ready for this event. I am proud at how much they have accomplised in such a short period of time . Mojito is still a monster and has a huge flat torque curve. Racing starts 8 am on Saturday. Wish us luck!

I would go with an engine that is available state side with easily available parts. I love the S2000 engine for its reliablilty and power. There isnt a more powerful box stock engine around with the same level of reliability. It is a tall engine so may not fit all cars. It isnt the lightest either and the six speed trans is a bit of a monster. That being said it is very civil for a liesurely tour and is very fast if you keep it between 5500 to 9000 rpm. The lack of low end grunt that alot of S2000 owners complain of goes away with the weight of the seven compared to a S2000 car. Go with the 2.2 L and it gives more low end grunt. You can find eng tranny combinations for around 3k if you look around. The V6 engines like the Superstalker use make good power are reasonable price and reliable. It will be a little heavier with its iron block. Than an aluminum 4 banger. I dont know alot about the ford motors in stock form they should be alot of fun and very reliable. It will take some money to get alot of power out of them. (230 hp range) Honda does that box stock. The Ford is shorter and more compact engine, not but much though. Love the Hartley engine just very pricey and thats before you mate the engine with a trans. I like his H2 model which uses a Busa head, crank, rods, and pistons in his custom engine case. It does away with the bike engine and he puts a bell housing with flywheel and clutch assy to mate to a transmission. It has the alt mounted on the other end with the dry sump set up. It is compact and really cool and makes 200hp. It cures the main problem with BEC wear on transmissions and saves some weight which you have to add back with another trans. It would be great with an Elite 5sp sequential tranny. You now have sequential shifting again and a proper reverse. For about 15k you can put this package together out my price range but it would be a trick set up.

What was causing your idle problem? First guess would be a vacuum leak. I would be interested in what you found.

Looks amazing how long have you had the wings? Your probably are going to need them to keep that machine planted at speed. We are getting ready for Texas mile this weekend. Wish we could get to Hallet to run with you this week. We will have to do it some other time.

I have had great success with Rhino liner. It can be color matched to the car if you don't want black.

Never new of the 21. I like the styling. It will be a beast with that v8.

I dont think that is going to be any more civilized than a 7. Not to mention that engine cost more than most 7s.

Has anyone here ever owned a Panoz Roadster. I have like these for the last 15 years they were always out of my price range but should be great fun. http://cgi.ebay.com/ebaymotors/Ford-Mustang-1999-Panoz-Roadster-Just-Like-Go-Kart-Black-Black-_W0QQcmdZViewItemQQhashZitem27b5846da6QQitemZ170549079462QQptZUSQ5fCarsQ5fTrucks

Amen I'm not an old fart but I try to imulate old farts as much as possible!

Mondo the physical dimension is the same it should be a remove and replace. It just has a different compressor section.
