After all of the headaches and issues I just want the car to run again and be able to drive it and enjoy it.

I know the dynojet is just a number but its fun guessing anyway.

I'm guessing 635.

Dear Lord I hope the belt doesn't break again.

647whp.

any reason you are leaving the restrictor in ?

GeneSch

Take the restrictor out. You have meth and fuel. You can always pop it in if its making to much boost, then open it up a little and keep making pulls.

Dimewise

My thinking was due to the 10% OD. But I was thinking about running it without it also and doing what you mentioned.

Matt Sorian is tuning it and he worked at ECS at one point so I have a lot of confidence in him.

Whatever it makes, it will be a fun ride. Pretty dam sharp looking too. Love the extra blackness

russ472

removing the restrictor will make a significant difference. I wouldn't recommend it to anyone not running bigger injectors and meth, but you have that covered. Why leave free power on the table? Go for it.

705 rwhp without the restrictor.

725 without restrictor plate

I'll play...715 without restrictor plate

Dimewise

I guess I'm a little paranoid to lean on it is all. Motor has 54K on it.

Thanks for the responses yall!

Dimewise

Man yall throwing out 700+ now? lol

schpenxel

Is 54K supposed to be a little or a lot? I'm closer to 200K, no restrictor, 3.25 pulley. Though E85+meth probably doesn't hurt

Dimewise

TBH I don't know whats considered a lot on these ls3's.

This is all new to me still. The fact you're going strong at 200k is awesome.

schpenxel

Yeah 54K is nothing, no worries there

07blkvette

What made you go with a 3.25 instead of 3.6? How much boost and what HP are you at?

schpenxel

Started out with 3.5" w/ restrictor and kept going from there. Kept opening up restrictor then just took it out then went to smaller pulley (meth was added along the way then E85 also)

Not sure on HP, haven't had it on a dyno

14psi is the highest I've seen

Still running Z06 exhaust w/cats so that's probably holding back some, but I just can't take the no cats smell for whatever reason

Dimewise

So youre around 700 then I guess?

schpenxel

Something like that I'd guess

Though my horrendous showing at 1/2 mile sure wouldn't support that

Dimewise

Just weigh the car and get a mph at the 1/4

schpenxel

Yeah probably going to do that soon if I can avoid the whole blowing up the 05 rear end thing
