That's an awesome build man! Love the ac! It must weigh quite a bit with an iron block and 80e. I know mine weighs 3750 with me in it, iron block and 80e. You get that 60 down and it'll go 9s for sure. I'm impressed with the mph, that pt unit must flow quite a bit. I'm wantin to upgrade mine from the on3 7875 to a pt 7675. To me it just seemed the exhaust housing wouldn't flow more.

I tell you that Trickflow cam is pretty decent considering the price! Hopefully they wont jack it up since it seems to be selling decent. I was getting around 18-19" of vacuum I think with that cam, and it was actually pretty quiet in terms of valvetrain noise. I get another!

I really need to weigh this thing. Maybe, its lighter than I think.. How much boost are you running with the On3 unit?

Im glad I saved a few bucks on it! It makes power and spools the turbo faster than the stock cam did. I've followed your build a bit. Didn't you swap out the trickflow cam?

Yeah I'm just a wuss that likes a smooth an idle as possible. Not that the TFS cam was radical (I think it idled at about 850) which in my mind seemed to high. The LS6 cam is 650 and I still think its too high lol!!!!

Thats odd. Mine idles at 650 great. If I were better at tuning, it might idle lower but I'm happy at 650.

Nice times. I assume those passes are with drag radials?

Yeah I couldn't get it lower for the life of me. I think these injectors (83lb Holleys) just don't like going any lower. Looks like you have a much better injector. I was also wondering if my plugs gaps (.022) are affecting idle. What's your gap?

I would think if they idle that low with the ls6 cam, they should with the TFS cam. The pulsewidth at idle would be similar, I'd think.

I don't quite remember the gap. The plugs haven't been out since September. lol. I want to say I gapped them at .028 though.

[QUOTE=bigmandengo;19264815]I really need to weigh this thing. Maybe, its lighter than I think.. How much boost are you running with the On3

It makes max power at 11-12 psi. I have had it at 16 and power just drops. Best mph is 131.5 and it was on 11 psi.

i went with alum bumper supports and fiberglass bumpers and alum heads on an old Type T I purchased in 87

thing finally went 10.80s and with no roll bar you get bumped off but it allowed me to turn the boost down and run 11.5s with one glory run at the end when the air was cooler

fun stuff the ls would likely weigh about 80 lbs more than an iron head v6 so it's not too bad.

those are nice numbers boostamuv!

It doesn't seem right for that turbo to be tapped out so soon. Maybe, you're having another issue.

I'm guessing it's close to 800 flywheel horse. I just assumed that it was maxed for a cheapy turbo. I wouldn't know what else could be a problem. Has pac 1218s so shouldn't be valve float?

Scored a craigslist deal to start off this winter's upgrades (I know its not winter yet, but the car runs too good to rip apart now). Gen IV aluminum 5.3 with flat-tops and 243s. It is a DOD failure motor, which is fine. Standard lifters will be swapped in anyways.

This is a 58x motor so instead of swapping the reluctor wheel, I'd like to make the transition to a MS3 pro setup to take advantage of the integrated 2-step, boost controller, traction control etc.. Should really be able to lean on this thing next year with the stronger rods.

Weigh your car yet? Our set ups are real close except your turbo and mines supercharged. I weighed in at 3837

No, It has not been weighed yet. The only place I know of to weigh it around here is the local truck scale. Any Idea how accurate those are?

Is 3837 with you in it? and how is your car optioned? (hard top, manual windows?

That's not bad considering your power options. My car is all manual Windows and hardtop but steel wheels. Maybe 50 lbs lighter than yours.

Any recycling place should have a scale. They weigh the trucks in ,and out . You could just go up to the window and ask. U just drive on and stop.
