Just a bit of an update on the Supercars Chicago Lexus SC300
We made
970rwhp
790rwtq

The best thing about it, we made 908rwhp by 6k rpms!!!!!!!! and it held over 900rwhp till 8500 (when we let off) even with a boost leak. It was around 34psi and fell to 31psi or so.

We were running a VERY conservative 13 degrees of timing on VP import. So with a bit more timing, and fixing the boost leak, and a hair more boost, we should see 1100+rwhp.

Oh yeah, the engine torqued so hard that the factory fan hit the fan shroud and literally it exploded into a hundred pieces!!!!! It was kinda badass.. LOL

I have this video in loop

awesome. that thing is a monster. and what a sleeper. congratulations. - Russ

 

You know I'm gonna like it! Saw this on Supraforums, badass indeed!

 

what's the powerplant?

 

It's pretty sure it's a stroked 2jz-gte (Supra Motor)

For the non-toyota people, The Lexus SC,GS, and IS vehicles shared the same motor as the non-turbo supra. The Turbo Supra had oil squirters and lower compression, but were very similar.There are numerous high hp Lexus SC's roaming the street. Unfortunately, mine isn't one of them.

 

Thanks guys.

Like SinisterSC said, it's a stroked 3.2liter supra motor. Motor should take about 1400rwhp they way I have it built, now I've just run out of turbo

 

wow, very nice set-up.

Good luck on your 1100hp goal

 

Congrats Chris! That is awesome power.

How does it feel on the street?

 

Thanks Jim. I haven't turned up the boost on the street just yet I wanted to be sure we had all of the tuning finished before I made some highway pulls

You coming out thursday night, if it isn't an oven ?

Chris

 

Nide ride, seen it in person and can't wait to see it running around at one of our Cannonball Runs.

 

Holy SH*T! That thing is SICK!

 

WOW - I have not seen it in person, it seems as though every time I go to Steets, you have just left, or when I leave you just showed up - Someday I hope to see that bad boy in person though!

 

Time to update this thread again.

 

Damn, thats insane, you guys really know how to throw down. I bought my first car off your lot and almost splooged over the cars you had in your garage, keep in mind that was 2 1/2 years ago, can't even imagine today!

 

Like Jamie mentioned, we dyno'd again and hit 1,006rwhp 825rwtq last week on the dyno. Still having issues holding boost, and the belt keeps coming off due to a waterpump issue. Fixing all of that and should see 1100+rwhp

Tech, thanks for the compliments, that's actually my buddies shop
