What tires do you plan to use? The Superlite Coupe guys with LS3s say they have to very gently roll on the power because they just break traction, and that's with half the hp. Oh lawd.

I've got Toyo R888Rs all around- 265/30/19 front and 325/30/19 rear. I'm definitely not expecting traction until probably 100. I'm also going to play with the wing angle since it will definitely help.


On another note, I've got a tentative appointment with Jeremy Formato at the Fasterproms youtube channel for a tune on May 14th, so that should be pretty cool. We'll see what kind of power it really makes. Also, here's my latest video I uploaded if you want to check it out.

Any new news from this build. Patiently waiting for a WOT pass...

Car is pretty much complete, but still waiting on the Recaro seats I ordered. I took it to Jeremy Formato for tuning but the torque management in the Gev 5 LT ECUs has been a pain. Basically you command a certain amount of power via the throttle pedal, but the ECU decides how much you actually will get. So you can see on a data log of 100% throttle pedal, and only 36% power delivered to the engine. We'll get it figured out. It made 478hp to the wheels at 2lbs of boost so at 16lbs it should be twice that.

Here's a quick little flyby, maybe 40% throttle-


Here is one of the pulls-

Thanks man. It's more of a weekend toy but I'll probably track it a few times. I still need to register it and a few other things, but it'll be on the road very soon.

Got the car tuned finally and it made 751 to the tires with boost falling from 16.5psi to 12psi from belt slip. I got a new idler pulley that should fix the problem so it should be in the low 800s with full boost. In the meantime I took a vacation to Guadalajara and saw a ZX-10R who I did a rolling photoshoot with.

lol Yeah Harry took care of the shipping and Dom was riding the bike.

Car weighs 2490 with all fluids and a half tank of fuel. Just installed the idler pulley last night for all the boost and have a Dragy coming so I'll see what numbers it puts up.

LOLz... 800rwhp @ 2500lbs is fkn nuts son!!!

I have had 2 foxbody's in the 2900-3000 range and until you experience what a light chassis feels like with some HP its hard to describe. Everything just works more efficiently.


Speaking of Dragy..... Here in Houston we had some decent air @ 75* this morning and my '13 did a 5.1 60-130 on a heavy a$$ set of 20's. I am going to get my 4.XX pass this year...

5.1 is moving for sure. How many times do you shift? Is it a 2-3 shift or 3-4? My car has pretty short gearing and second only goes to 75 since it's a Porsche box where they need to compensate for a lack of torque. I think my fastest 60-130 would be a 3-4 gear pull. We shall see!

I generally start at 55mph in 3rd and grab 4th..

In 3rd 55mph is pretty lazy but I just don't see shifting 3 times being quicker. And on 20" drag radials it damn sure doesnt hook anywhere in 2nd anyways... But I have a couple more tricks up my sleeve coming soon... a set of locked out LM1 cams & a 3.25" pulley

Thanks man. More content coming soon. I installed the idler, reflashed a new tune, and had a Dragy delivered yesterday. I'll get some videos and real world performance numbers very soon.
