Suspension, Tires, or both?

[Sam88gta1]

For sure, any time I take it out I log, make adjustments, then the next time I go out I flash and log. Matter of fact, in the 100 or so miles I have on it I've logged every single mile.

The FPR is boost referenced, and I've verified it climbs 1:1 w/boost settling in ~55psi under full boost. I have my IFR scaled appropriately. Strange thing is I am showing high duty cycle for the amount of HP I should be pussing, at 6200rpm and 12psi I am showing 80% duty on 80lb injectors. Not sure how much faith to put into the duty cycle calculation, but I've seen cars with huge power on 80lb injectors (pump gas).

Set base fuel pressure at 58psi with engine running and no vacumme line attached. What is it set to now?

Suspension, i was running stock suspension with 28x10.5x15 E.T. Streets and couldn't hook worth shit, my buddy wanted my welds and offered to trade his sve lowering springs, sve upper and lower control arms(not the fanciest company but theyre better than stock), and bought me new kyb shocks and struts plus his 17x8 saleen replicas with 17x9 in the back, they have decent nitto DR's but my car hooks real nice now. So I suggest just getting a nice set up upper and lower control arms it should help out a lot. I never realized how big of a roll suspension plays.

Shit ! Posted all that for nothing. Just read you already have uppers and lowers, sorry

I got my injector tables scaled for 3 bar (these are 80lb@3bar) since they should be plenty large and it's easier on my pump at 43 vs 58psi base.

Ok then, You're the expert. Keep it at 43.









Which do you think is more important ,strain on the pump or maxing the injectors past 80% duty cycle?

Well thats my concern now, I set it up to run at 3 bar since according to the injector calculators I shouldn't even be close to 80% duty cycle until ~850fw, with 12lbs I highly doubt I'm at that point, if I am actually at 80% then I'll up the fuel to 4bar and change my injector data. So back to the question, does it seem reasonable I'd see this kind of dc at with my combo?

FYI I put those tires on in 2002.

Who is this?

Can't be talking about the same car, the build date on these wheels is 06, and the roller was built in 07-08.

That's the original owner of the roller. And those tires may be older than the wheels on the car. A lot of parts were bought across several years throughout the entire THR build experience.

And the roller was picked up at Fun Ford 2006. Do you want the pics?

For sure I'd like pics, the guy who owned THR forwarded me a bunch of photos throughout the build, but I'd like as many as possible.

When the tires were bought I don't know, I just know the Welds have an 06 build date. I'm sure they are at least that old and they are getting replaced as soon as I get back into town.

Lemme guess, now you know more then Brooks? This is how I became the "expert". And BTW, looks like Brooks was right since I am peaking at a safe 80% dc, I was just inquiring why I am seeing even that high given my combo.

Me:

I also bought some 80lb (@ 3bar) injectors, do you think I should run them at 3 bar or at the factory 4 bar pressure (they are 96lb @ 4bar).

Brooks:

Those injectors will be fine at lower pressure for your power level. Your fuel pump will appreciate it as well.

Can you post it? I have some photos of it at FFW, but it has a for sale sign, we're you selling it or THR? He made it sound like he built the roller, you wrecked that day and bought this roller, didn't sound like you had it built. Of course from what I've read he is a total lier, but the "for sale" sign at FFW threw me off.

I'm just enjoying the show. I'm no expert, my car spins too
