Default My slow GC8 build

Well I thought I would start a thread documenting the slow assembly of a GC8.
The car started as a jdm RHD import and has been slowly modified over the years.
Here is a link showing the first builds.

http://www.youtube.com/watch?v=Jf94WIS1bCk

The car was a solid 10 sec car but I felt we had reached the max potential with the setup.

So we have stripped her down and trying to produce a 1000HP 2.5lt all alcohol motor running a twin scroll UR GT4202 kit.

the goal is to get into the 8's with a manual box.

The first order of the day has been to shed weight.we have gone to an all composite body, doors,fenders,trunk, Aluminum hood(lighter than the CF one I had )




Today it came out of the spray booth.

I had ordered a drivers image intake manifold. when I received it I was disappointed with what had been done and between Ron and Gregg they decided to fabricate a new one the new manifold has intake horns and nicely finished porting, I hope it performs well.
If it doesn't I will have an extrude honed stocker waiting in the wings

1st manifold.




2nd manifold.






thanks again gregg for a nice job.

Suspension is one of three manufactured for ESX for thier drag car.
I hope it works well the guys at perfection are very helpful so I am sure they will help me tweak it.
The picture shows the helper springs on the front but they actually go on the back struts.

The rear suspension parts are from Poltec (trailing arms, lateral links) for weight reduction along with a Torqline CF drive shaft and ultralight brakes from The Brakeman LTD and a hydraulic handbrake so there is no rear drums to add weight to the rear unsprung assembly. Tyres are be 10" Hoosier slicks all round.

looks good so far! Keep up the good work!

question though...is this the one that hit the hydro pole when the steering locked while being towed by an suv? I saw that vid a looooong time ago and this looks really familiar in the pics posted on the video.

Yeh, I thought it looked familiar.. Sorry to hear that, i wasn't trying to rub it in or anything. On the bright side,this thing should be a beast when completed!

I'm also curious as to how the intake manifold solution will pan out.. Unfortunately we don't have many in the way of solutions on the market. Maybe I'll have to approach Ron as well for one. He's a good guy to deal with.

Because torqline says 1400hp proof and the quality ext ,if you look at the two side by side there is no comparison, I believe from looking at the torqline unit it is filament wound construction where as the actp is a hand layup job, could be wrong though.

US dollars, they come from the UK 1300-1500 pounds landed USA
One thing that I find strange since I changed to the CF shaft I havent broken one rear axel up until that point I had gone through 8, 6 stock sti and two upgraded shafts from the uk. the second set of upgraded shafts have taken all I can throw at them without a murmer.
I wonder if how the shaft loads up on launch helps the shock to the drivetrain?

I believe that carbon fiber drive shafts to twist somewhat on the launch to absorb some of that shockload, which might be why you aren't breaking the axles anymore...

It's hard to say though which is the way to go for drag racing though.. The steel stocker would be dead reliable and take all you can throw at it, while on the other hand, the CF one although lighter, is likely not as bulletproof.. It would be crazy the way to go for road-racing though for sure. I'd be curious to see how well the CF shaft holds up in the long run

I'm thinking about getting in on one later on, but want to wait to see how they are holding up after a period of time.

Have you used this shaft yet?? Does it wobble at all at speed or introduce any vibrations or anything into the car??
