I will be starting my next phase for my car this month. I plan on some new head changes, larger fuel system, some other neat tricks and maybe 4 liters? I am hoping to come close to 30 psi WITHOUT welding my heads. This will take around 4 months of R&D so I hope in August or September it will be finished.

 

yowza, Well, I just saw a Carrera clutch cost 28k, so it is all a matter of perspective

 

Really, Jamie? On DOT drag radials on the street? That's impressive.

 

I've managed "full power" which at the time was 1,101 at the top of second in my old Supra as well on a very nice strip of asphalt near my house (with 325/50/15 MT Radials). Having driven the same strip with 838, I can say that the difference between 800 and 1,100 when it hooks is night and day.

As far as the heads lifting, is everyone using stock sized studs when this happens ? I know on one platform we use 1/2" studs, however on another platform we not only went with the larger studs, but also machined an extra set per cylinder to keep things down.

 

running stock headstuds?

 

nope arp i beleive.

 

If you are depending on ARP for high HP P cars... You will have some problems...

 

custom 11mm head studs here.

PS I will be ready in a Month. No R&D the company that is doing my work has achieved this goal already. Details to follow as I finish up.

 

I think there are a few builds currently underway that should hit the 1000 number.Honestly its not a matter how much power you want to make, its a matter how much power can you afford to make.I am hoping my new build will be in that very exclusive club, bottom line is even if some make that kind of power the car will most likely not be very street able or a least driver friendly. I think thats taking away from the TT...but how nice would it be to have 1000 HP!

 

All the tuners are using the same ARP direct replacement head studs... which have been giving some problems. The trick is to go with a iron block and bigger diameter head studs... then we can run crazy PSI... but that may never happen... way too much R&D...

 

I would say my car is very fast, makes over 800 rwhp and more importantly I drive it daily! I dont understand why there is a misunderstanding about high hp and drivablity. I might have a small advantage because I have a 3.8 liter; however, everyone who drives my car comments about how docile my car feels. I think if your car is built correctly and tune by someone with knowledge of high hp cars you will never know it until you turn on the EBC!
Have a boosted day

Still on the fence on who is going to be tuning my car, I did end up going with the 3.8 L as well, I was leaning to the 4.0 L, after speaking with a few of you guys the 3.8 won. I am hoping my car will be as tame to drive as yours is.Only one way to tell.......the first drive will be the test.

 

I and a few friends of mine have gone this way... the numbers speak for themselves... I talk to Todd Knighton regularly... one will have some very serious issues to overcome. Don't believe everything you are promised... no matter who that may be....
here are pure facts...
we run gt35rs with .82s A/R at 1.5 or 1.6 with significant headwork... and that does not break the 900 rwhp barrier. At that level, 1 psi is about 25 rwhp according to Todd... therefore if my math is correct you will need about 31 psi to hit the 1000 rwhp...
If you do the 3.8L, and if it holds together... something I have yet to see besides Rob's car running GT35rs.... you may pic up 40 rwhp on top...

bottom line- Aluminum block does not like boost.... So unless your willing to take a chance just for bragging rights I tend to say you will be at 1.5 bars...
and somewhere about 900 rwhp.
Good luck,
mark

 

LOL
I know all about it... lets see what happens...
Im waiting for some clutch replacement parts next week... if it holds then Ill be happy , if not ill have to go another route... other then that the car has been ready just no where o go in the extended winter break we have had in Chicago..LOL

 

One of the reasons that you have not seen a 1000hp Porsche yet is because honestly most shops are to secretive. Do you know why the LS1/5.0/4.6/etc. have done so good is because people work together and are not a bunch of arrogant *******s. Maybe if people learned to work together we'd get **** done. Don't give me the excuses that its because of money, because honestly they could make more if they worked together. I know some may HELP each other some, but not enough. This doesn't relate to everyone because there are some people from certain shops that have helped me along the way, but for the most part the others try to be to secretive.

It's funny that some of the big names wouldn't even come congratulate people like me who have thought outside of the box and built cars that make just as much power as people who have spent $25k to do a build. I guess when I finally build my motor and max out the turbos I'll be laughing because I did this for still less than $20k and will be making some insane power.... Maybe the younger guys are the smarter ones because we can do more with less... LOL!

And for those dissing Aluminum blocks maybe you should look at the LS1 because it was aluminum with 4 bolts per cyl. they said it could never make a lot of power, but if I remember correctly they have made close to 2000hp without any problem. Hell they said the same thing about the 4.6ltr Cobra/GT motor... I guess the people that buy the expensive aluminum blocks are just dumb.. LOL!
