Rajca's Project CL-S6 Car

Rajca is planning on running a ginormous turbo.
Its possible that it may be too big for the motor though, so it may have a hard time staying in boost.
I remember what CL hes talking about though, the one in the 400s. It was a silver 03 IIRC, a guy that worked for Greddy at the time built it (hes a member here).
Actually, I have the magazine article:

^^thanks for the link, I hadn't seen that before.
Regarding the turbo application, c'mon people. It's obvious that we're all assuming the chosen turbo is going to be optimal efficiency for the chosen application. There's a reason there are turbo efficiency maps for different turbo specs for different applications...
Rajca, also keep in mind that these numbers are 6psi @ 10.5:1 compression. If you plan on lowering compression, you'll have to boost a ton more to reach similar numbers.

from what i can remember their were two ppl that were pushing over 400whp. one 468whp or something like that on 10-12psi. its blurry bc i dont know the exact specs but stock motor. theirs a spring and retainer clip set out their already. need to make custom valves and dont know what im gonna do with cams.
one way or another, im gonna hit my goal. weather its more boost or more spray.

try some nitro-methane fuel

also it is a whole lot easier to run higher boost with high compression, when you are not limited by pump gas

try looking into some mdx cams, i know they are different but not quite sure if in a good or bad way
try some nitro-methane fuel
(like they use in top-fuel dragsters), that will produce some extra power, while draining your pockets
yeah depends on the flow rate of the turbo itself, and also how hot it actually makes the air when it boosts it to a certian level

lower compression with higher boost will yield more power than high compression with lower boost.

High comp plus boost = detonation issues
The loss of low end torque is true when you have a low comp NA motor, but boosted you'll make more power anyway, and safely.

but the turbo will spool up faster with a higher CR ratio, so you have a broader/wider powerband, which is really nice and kinda neccesary for a street car (for driveability) (should also be better MPG too)
and yeah a low cr will let you make more power, but that power will geaneally be peakier (upper RPM's so not as usable on the street), but for rajca and it being a track car, it does not really matter, cause he will proably be staying in the upper powerband anyways

Yea, but the grade of gas varies too much to run high comp on a turbo motor safely, even if it is built. Pump gas at one station can be a certain octane one week, but the next week could be slightly different at the same place.
If you want the turbo to spool quicker, get a smaller turbo. Hell, build a hybrid snail (smaller hot side, larger cold side). Dont sacrifice reliability and depend heavily on pump gas. Its not worth the possible outcome.

or hell even a variable geometry turbo (if we could even control the F***er like a factory car does, not saying the aftermarket could't just be quite a bit of work to get it to work right)(and have enough options in the actually size of it)

keeping the tread alive. been working my ass of at my work. just to get the build going and paying off my school loan.
but anyway. but a few more parts made by p2r and got the shifter bushing. now im gonna make some custom ss clutch lines at work. im gonna get the ones with the black rubber on the outside bc im trying to make it as sleeper and possible (yes i know, ppl will see the turbo). but still. want little to no bling under the hood.

Dont go crazy with the clutch lines. The hardlines are better. Just replace the rubber lines on it.

Ok.
It honestly doesnt matter if you use silver or black, you cant even see the line when you pop the hood.

I LOVE THAT RUG!!!!
I used to play on that with my hot wheels cars when I was a kid.
Ok, ok, I still do.

And look around this country, every one that isnt living on an Indian Reservation is an immigrant in some way or another.
