Re: My 3400 T '88 camaro

i typically go for .024-.025 buty that lil bit of difference between what u have now and that wont do anything for spark blowout

Re: My 3400 T '88 camaro

Well, it used to run fine, even at 18 pounds... I think the plugs are just fouled. I'll replace them.

I guess at 18 psi, it was never "loaded" very well cause it would just spin the tires on the street. (any gear) So, hard to tell.

I'll figure it out.

No, I don't. It's full interior. It has nothing as far as SFC's or anything. No power options.

Id say 3000 - 3100 ?

I'll stick it on the scale next time I take it to work. It's a dead accurate scale within 1%. (I should know, I calibrate it)

GVWR minus capacity, assuming no weight reduction mods. And for comparison my car, which had AC, t-tops and auto trans weighed 3153 factory curbweight.

Re: My 3400 T '88 camaro

Nah, some of that **** is hard to spot when you aren't looking for it. I have a rocker that wouldn't adjust to the correct preload, couldn't for the live of me figure out wtf it was, even bent a pushrod slightly by accident trying to preload it, it just wanted to be way more preloaded than all the others which were really close to each other, at first I thought my lifters had unpumped themselves from sitting, a few of them had actually, so i resoaked them, and tried a couple different ones, but still it wouldn't preload....so then I started wondering about my cam lobe, but all the lobes looked fine from what I could see of them. I finally while not even messing with that, noticed my valvespring was broken, but it was still on there and looked perfectly normal at a glance, sometimes its hard to spot things like that. I had never messed with the springs, but did have a new cam and lifters, so I looked at anything and everything but the actual problem.

Re: My 3400 T '88 camaro

11.26 @ 126MPH - 15 psi.

The car was movin'.

I went on to win "Street Warz" yesterday which is basically an 11.50 index race ran on a .400 pro tree. Got a trophy, some cash and a 200$ lucas prize pack.

I brought the boost down to about 11-12 psi through the mufflers was about 11.50 - give or take, maybe I was sandbaggin' a bit.

Fun times !!

:P

No doubt it'll go 10's with a bit more boost.

Re: My 3400 T '88 camaro

I didnt take any vids. It was kind of a hectic day. My buddy blew an axle in his Cobalt SS-T and towed it using my trailer so I drove the Camaro on the street for about 150 miles. It was FUN.

The track photographer took a bunch of pics, I'll link them when they become avail...

There should be vids of all the street wars runs, but it was an index race and I had it dialed down to run 11.50. I'll link the vids when the track puts them up on their site.
