Neil,

To be running that power @ 1.3 bar you would need larger valves/ports, like the GT3 heads and maybe 102 or 104 mm pistons.

None the less, EVO has 830 @ the wheels and until someone posts something better, they are the current Top Gun. That engine is producing well over 900 hp @ the crank. I have reliable info. that the car almost jumped off the dyno at 5000 rpm's.

 

We are uding modified gt3 heads

 

I knew you had to be. Our current effort which is soon to be ready incorporates GT3 Cup heads, Inconnel Valves (intake and exhaust) and custom springs and lifters. The heads are ported, polished and grooved for three way metal o-rings. The combustion chambers are machined for the 104 mm pistons.

We'll find out soon enough if it works or not.

 

Neil,

Can you tell us a bit more about the Gemballa GT3R EVO. The information I have says up to 1.8 bar, GT3R heads and a compression ratio of 8 to 1. They also say it has a dispacement of 3.8L by changing the rods, however that doesn't make any sense. They either had to change the stroke of the crank or use 102 mm pistons. In addition, if they really had an 8 to 1 compression ratio, could they make 750 plus rwhp @ 1.3 bar?

I would appreciate if you would shead some light on this. Thanks in advance.

Chad,

Did you see this post on Rennteam about the Gemballa GTR650?

If you buy a PSI complete car it comes with a warrantee’s for that particular car I know all about that as my friend’s equipment went up in smoke.

 

Soory about what happened Fred.

Congrats to Todd!!

 

I just saw that Gemballa Post - OMG

Nice Job EVO!!!!!

 

Chad this time isn't wasn't due to suspension but some sort of debree that his the CF Intake aways the suspension area. It's just that SCarGO CF material brittle.

Since this has happened at least 5 times to customers, why doesn't SCar go learn from customer experiences and improve the CF Intake to avoid such mishaps. I have talked to Rob and he simply says that its' not his fault. Sorry to say but if 5 people had this happen too, I say that Rob needs to do better Q&A and release upated release.

Can't you tell that I work in the software/services business.

But again, the SCar CF Intake does prodcuce power. They just need to create soem kind of shield to prevent debree from hitting and finding a way to compensate me, which is fair but I know he won't as I've asked.

So I therefore ask all 6speed members to email Rob and have him send me a new CF Intake at a minimum. (one can only dream

 

Who are the major tuners involved in this shootout? GIAC, FVD and SCargo?

 

Fred... I'm really sick to hear about your car. I have some turbos sitting here that might work... ask Rob, he'll know If they'll work I'm only 3 hours away.

Also, ask Rob if he can have the intake tubes made out of Kevlar rather than CF. When you look under most race cars that have inner fenders you'll see they use Kevlar but, it has to be bagged and not a wet lay up or the resin will crack ... tuff stuff

 

Sorry to hear about your car fred. At least you're in Vegas!! Must be something fun to do there

Perhaps kevlar fiber (or carbon/kevlar fiber) should have been considered rather than carbon fiber for this very reason... carbon fiber is very rigid but brittle... kevlar isn't as stiff, but very puncture resistant and doesn't shred... also, the resin compound has to be tweaked to keep it bonded together better... race cars often use CF for the body and KF for the wheel-wells to prevent road debri from being shot through the wheel well by the sticky race rubber.

 

Sorry to hear about your car, Fred... always fun to follow your buildup, and car looks great... good luck.
