You got a ******* 30R!! Turn that **** up. IDK what kind of boost your making but I'm sure it's not near 22 if your only putting down 325. Turn it up to 22 and get down that track. I run full weight and 22 psi out of a turbo that could fit in the inlet of yours and I trap 3-4 miles an hour faster than you when I run your et's.

We have someone who works almost exclusively on ecotec's here in Mass that can tune you up right. I wouldn't be surprised to see another 50 whp with a proper tune. You have so much potential with that car I want to see it run hard!!! If your interested I can give you the info.

 

I ended up not working today so I went ahead and put on the limit straps. There not accually straps yet, they are small chain. The straps are still being sewed up but I have ran with these and dropped 2 tenths of the quarter, but did not have the footballs in the rear. Now I have the footballs and these, so we will see

 

the tune is the way i wanted. its a nice, fat, safe tune. stock timing. boost holds around 19-20 psi. makes 325whp and 340wtq on a superflow chassis dyno. the motors coming out soon to be built and i'll be pushing 26 psi then with this turbo.

 

damn dude, we got over 400whp on a gt3071r on 22 psi and meth.

 

its on 19-20 psi, no meth, stock timing. 340 wtq as well. what kind of kind of dyno was that on and what were the torque #'s?

 

I like that idea. Might have to try it. Was that bolt there, or did you have to drill it? Its been a while since i looked under there, so I don't quite remember.

 

No, had to drill the hole I leave the bolt through there with two rubber gaskets so water dont get in and possibly rust. As for the bottom where I connected it to the plate on the spring, the hole was there already.

 

suspension chain is ******* genious. Thanks for posting that up. I've been trying to figure something out and you just helped me out.

 

Chain will work but I would recommend real limiting straps as they stretch and allow you to preload better.

 

Your welcome.

Yea I have a buddie hold it down about an inch, but I do have straps being made.

 

Yes it is. But they're more effective with some air shocks in the rear. Kinda like a wheelie bar does for FWD vehicles. Strap the chains in place, then fill up the air shocks and the suspension has nowhere to go. Footballs and "drag bags" can only hold so much pressure. You're not going to be able to get those chains in the front running a properly sized drag radial though.

 

I am putting a set of 23.5/8.5-17 drag radials on my car. For the footballs, I have a buddie pick up on the fender then fill them up as much as possible, have not got to use the footballs yet but just the chains and I went from 13.3 to 13.11.

 

with a proper set of slicks, no reason those chains shouldn't work. the slicks I used were way to big.

 

Like I said, a proper sized drag radial won't fit. For those of us making power and have a drivetrain to hold it a 23.5 x 8.5 is a waste of money lol.

And instead of the footballs just buy a set of Monroe air shocks. Not the best handling in the world, but you bolt em on, run the air hose into the trunk, and fill and deflate as desired. I believe the MA826 fits our car and rings in at $69 for a set at your local advance auto. Much stiffer than some rubber baggies in your springs.

 

I am tuned, and was told that having a smaller tire that is going to grip good is going to get you rolling quicker.

 

link to these shocks, very interested

 

This is true... but the sizing is specific for gearing. The diameter of the wheel acts like another gear, and running a bigger tire will let you trap without shifting, and will also limit any wheel spin. This is how i understand it.

 

properly sized tires is key. too big and you lose some acceleration. Too small and you have to take an extra shift, hello 4th gear, overdrive gear, lost acceleration.

 

ive always heard "run as tall as you can"

 

sounds smart, you should do that. Throw some 26" dr's on and let me know how that helps you.

 

What size tire do you run?

 

if they dont rub obviously hence the "can"

larger footprint.

245/45 i believe

 

My forth gear feals just like a continuation of third.

 

it may feel like that, but you can't deny the overdrive gear man. I continue to pull in 4th against a 50trim srt swapped neon. That doesn't mean that I want to shift to 4th in the quarter.

putting the biggest tire on for the largest footprint doesn't equal to uber fast times. Properly sized tires will net the best results. It's a science, you should know that.

 

properly sized for drag racing is usually a taller tire IMO. the reason i say this is because you need as tall as possible to hook up and no more. i dont mean to infer running a super tall slick if you dont need it. however, you need to run as big as you can to hook up properly. also, a taller tire would help with that 3-4 problem.

look at alot of drag racers, taller tire, with a shorter gear. traction and gearing = win.
