9's at 140+ through stock LS1 TB/2.73 rear 10bolt :)

[Orr89rocz]

EDIT: Got into the 9's this weekend. See last posts

I thought i'd share this here since i'm running some 4th gen parts on my 3rd gen. Shows you can go pretty quick on stock stuff.

Ran my twin turbo 401 small block 89 Iroc-Z today on 12, 13, and 14 psi boost.

Motor uses a victor EFI manifold with intakeelbows.com 90 degree elbow and stock LS1 throttle body. Nothing else really special, strong bottom end, Dart SHP block, AFR 195 heads, Mike Jones custom cam, etc

Rear end is a bone stock 10 bolt from some 99+ car with zexel torsen diff 2.73 gears. No girdle or anything. Previous 10 bolt finally broke a spider/worm gear tooth and it was making some noise and slipping on gears, chewing up other teeth alittle so I dumped it. Needed a quick spare for racing today so i put in the other 10 bolt late last night.

Car should go 9's with abit more tuning and harder launch. 93 octane gas no meth, etc.

Good Job man. It's trucking on the big end. 9's will be no problem .

[SPEED#1]

Damn boy that car flies on the top end. What rpm do you leave at off the line? WHATS UP WITH THE BURNOUTS OUT THE GATE TOO....MAN THAT THING DONT HOOK LOL

[Orr89rocz]

I brake torque it up to about 2400-2500 then floor it. Think it flashes to near 4000. It hooks just fine, spun just once for a split second

[SuperSlow02]

why were you beating up on those poor mustangs

awsome times man

[Orr89rocz]

my track was flooded with stangs and usually is... some 4th gen fbods but mostly stangs. They wanted to play To bad i didnt get to line up with some of the other ones there, one was doing high 10's and another looked very fast but didnt see him run. That cobra was no slouch tho, 11.0's at 128

[silverz28camaro]

wow congrates, yeah those 2.73 gears are what makes the 10 bolt strongish. big pinion gear!! get that 60 down and 9's no problem.

[98blueSScamaro]

Sick ride for sure

[T/ALT1]

Nice times, looks like a 12 second car maybe but flies when the boost comes on. You need some slicks on that bad baoy and 9's would be easy.

[Orr89rocz]

I have ET streets on it and it hooks fine, just doesnt leave hard enough... need to get into boost on the launch

[RapidRick]

You sure weren't kidding around on the other thread (Torsen Rear).

That's 1BADTURBO, in a mild mannered sort of way!

Congrats!

9's ?...
won't take but another trip out to the strip.... :

[LS1 SPEED]

very cool! congrats

[kinglt-1]

Very nice times! There is nothing wrong with leaving the line a little soft, especially when you drove the car to the track. 10.0 is an awsome feat on the stock 10 bolt imo... sick setup you have there, congrats!!

[02sleeperz28]

Congrats nice setup indeed!

[Villain281H]

nicely done!!

Just went 9.97, 9.93, 9.86 all at 139-141 at my home town track saturday. PRP

Then went to MIR sunday and went 9.86, and 9.73 at 142 mph. Last run i mixed in some race gas, cranked the boost up to what I was hoping to see 17-18psi and went 1.49 60 foot but blew a vacuum line off the intake on 1-2 shift and power dropped out. Says i hit 16.6psi on the log but car didnt run like it i guess. Still ran 9.73 but it wasnt liking the street tune with the 110/93 octane mix. Car was richer and just didnt feel as strong as I expected it would be but that leak must have caused that. Would have been a 9.5 pass i think at near 145 mph I bet

AWESOME CAR MAN!!!

Lets see some engine pics!

Compression on the engine?

Love to see the 3rd gens sneek up on people.

[Orr89rocz]

It looks better in person, i need to get better pics. Here's when it was just about 99% done




Just 9 to 1 compression and 14 psi so far. Should handle 16 on pump gas no problems but havent taken it that far yet

[JRracing]

Very impressive car. You need to get a brake in it so you can bring it up to about 4K on a tweo step. LOL. Wouldn't that be something???

[TTA1437]

That is impressive man! Who did the manifolds and what intercooler is on this car?

I would love to do this to a third gen.
