What kind of numbers should I expect to get with this,new project car ?
All mods are in sig 98 Z28.
Hoping for a 10 sec time slip come next racing season, anything missing that I need to have yet?
Waiting for Spring is going to make for a long winter....

Sigs dont show on the mobile version of this site, and they don't show in a year when you change you Sig and people were wondering what your setup was.

If you don't get a 10 sec slip with that, I'd burn the car to the ground.

Running 6 psi it put down 540 through a TH400. Missing from Sig is the meth kit.

I was hoping for some more opinions or ideas.
Lots of views, let's see your thoughts.
10 second capable,or what else is needed?

Afr225s and the cam alone would get you right sat the 10 second mark of not in it. I don't see why your even questioning the setup. If you've paid the money for all those parts which are top notch, why are you guessing it's capabilities? That is easily a single digit car.

Car was a good friend of mines, I just acquired it . It was in storage for 4.5 years when I got it and just had the Procharger and 4L80e swap done , Trans had 25 miles on it .
It's not a completed project and I am starting with a lot of unknowns about forced induction and exactly were the car is at.
I did a shake down run and found it is in need of some work, best was a 11.43@120 1.64 and no matter what I did it would trap 120 and no higher.
I've been told that the car could be as high as a 135 mph car, but clearly something is holding it back.
I badly want to finish his project and get the 10 second time slip he was shooting for before he passed away.

I don't see your tire listed. Kinda hard to guess....

Nitto 315/35/17 at 15 psi
I am thinking a 28" tire will be a nice step up . Once sorted out I probably will run out of gear .

F1A and a stalled auto, 10s is easy with a real tire on it. I didnt see how much boost though.

Dyno sheet I got with the car shows 540/440 with 6 psi of boost thru a TH400 w/ a brake and a 12 bolt Moser w/ a spool .

That motors stout if those numbers were through a th400 and a 12bolt, car will 1.6 sixty foot in its sleep and go 10s no problem

redsscamaroboy

I agree, he put together a hell of a machine, he and I both thought 10's were NO problem .
I just need to sort out what's currently holding it back.

Do you have access to HP Tuners or Efi live? A simple log would likely give you a good indicator assuming everything is okay mechanically.

Good plan, I do have HPTuners but am waiting until I purchase the innovate wide band set up this winter to try and log .
Car is tucked in the garage for that long nasty winter.

I'd run dot M/T 28" tall tires, your 3.73 gears should be just fine with your combination. I don't see you running out of gear. I had an F-1A at 18 psi with 3.70 gears with 28" tall tires, and did not run out of gear. 6 psi is very low boost, especially for an F-1A. What pulley is on the head unit? Bob

redsscamaroboy

Bob, I'm not sure who made the pulley .
It was something custom that was done when my friend still had the car. I just know he had it made and was wanting to build a short block for boost then change it out.
Being new to the Forced Induction LS world I'm confused how the 5.3 can take wicked boosted set ups but this LS1 is on borrowed time at 6 psi.
I'm still trying to educate myself without tearing this car up first .
I'd love to change pulleys and sort out a good tune with a proper fuel system . I just need a lot of help from sources that know what needs to be done.
I really appreciate all the info , comments and help guys.
Thank you.

I don't know who told you it is on borrowed time at 6 psi, but a healthy LS engine can typically handle 8 psi for a very long time, provided it has a good tune. Bob
