Probably not. But Chad would be a better person to ask that question to, since he's already experimented with both.

I'm personally staying with 3.6 liters.

 

Div - great video! Your car is a monster and there is nothing as fun as racing bikes on the highway. I recently ran a ZX-10 with bolt-ons and like you, was not running full tilt, you can see results here (if you'd like me to take this link off your thread please let me know):

I hope you make it to TX2K8 in March 2008 as I would love to line my street car up with yours...

gaining .4L just from overbore wouldn't do that much for spooling charsteristics. Stroke (due mostly to the increase in piston acceleration speed) has a far more profound result.

I haven't ever had a P-car head on a flow bench but I would be willing to bet that any gains would be the result of unshrouding the valves. Though you may need to reangle them to take full effect, and even at that I tend to think any theoretical gains would be held at bay by the thinner cylinder walls.

IMO, keep the bore down, thicker cylinders, and more head gasket sealing surface area.

Letting the hot side breathe and keeping the backpressure down is almost free hp in comparison to many other changes. It's hard to do on such a small motor and still have something reasonable to drive, but it can be done. Anything around 1.2:1 pressure ratio is doing good on a street car.

 

Great vid, Peter. Thanks for posting it!

If I'm back from Iraq in time, I will definitely be at TK2K8. So will my buddy who also has a 996TT with the essentially same setup I will have.

I want to run you, as well any other big-power Supras or Vipers I can find. I don't think I'll beat the *really* big-boys, but I think I'll put up a much better fight than some people might expect me too.

 

Div - GREAT! I can't wait to meet you and have some fun on the streets. My car is not a "big boy" so ours should match up nicely...

Peter

 

Hopefully by TX2K8 I'll have turbos that will allow me to pick on something more than just heads/cam LS1s There are going to be a ton of P-Cars this year it seems like. You still looking at getting one too, Peter?

 

you guys may think he is being sarcastic as he has 1006RWHP but he is being honest

gotta love supras

 

so so true and still a 3.0L.. but who knows? peter has a couple of tricks up his sleeve

 

I hope we can meet at the Texas Jam, I think we all can play.
Robert

 

lots of fun..

thanks for sharing..

would you like to meet a turbo busa from north carolina?? .. 8.43 @ 183+...

street bike..

.

 

Sure, why not? Have him come to Houston, TX March 2008 for the TX2K8 event.
Peter

 

Peter
How many guys are you bringing from RSI to the Texas Jam? We should have next year Texas Jam at RSI? My car will be in Dallas Friday praying on any of those D boys...if they are not hiding

 

I do not think anyone from RSI will be coming, but I am not for sure on that. I think Peter said in another thread he was not going to be able to make it to the event. It would have been nice to have it hosted in Houston. I'm sure a LOT more cars would come out of the wood work. Esp the cars from Austin.

 

wow.. thats fast.

 

Right on !!!
