First off... The LS1 is totally stock down to the manifolds, MAF, PCM tune (havent even scanned it yet), all of it. The rear is out of a 95 T/A with 2.78 gears. The 4L60E and converter are stock. Suspension is stock V6 with some polyurethane here and there. And I really dont know how much she weighs, probably about 3300lbs. The only mods: custom Y, no cats, flowmaster 3in. in and 3in. out. and some BFG DR's.

1st run 2.04 60ft., 8.76 @ 81.95 w/paper filters
2nd run 2.00 60ft., 8.76 @ 81.78 same
3rd run 1.98 60ft., 8.63 @ 83.30 no filters
4th run 1.97 60ft., 8.61 @ 83.21 same

I think with that MPH theres some lower ET's in store, but the suspension is going to need alot of work first. I already have a TR224 cam for it, but I'll need to get a converter and gears (it wasnt even done with 2nd gear going through the traps) before it goes in.

Alot of work is in store, but thats what makes it fun. What do you guys think?

 

not bad at all, for the gears, lack of suspension, and totally stock ls1.

 

what was the 1/4 mile times. or what does those 1/8 mile times equate too.

 

Our track here is only an 1/8 mile, but those times are good for high 12's or low 13's.

 

those are some impressive numbers, goodjjob the Ls1 rules, plus you have pretty cruddy gears that are holdin you back

 

great results. a little gear and a little grip and you will have it made.
maybe we will have to get together for a battle of the hybrids next season once my swap is done.
keep up the good work

later

Typical conversion from 1/8 to 1/4 is to multiply the 1/8th time by 1.59.

Those times equate to roughly 13.93 with filters and 13.77 without filters.

 

Are you sure that thing weighs 3300lbs? I would think it weighs a bit less than that. A stock RS with a 305TBI should weigh close to 3300lbs, and I thought the LS1 block was supposedly 300lbs lighter than a standard iron SBC. Aluminum heads should also account for 50lbs (though I don't know if that 300lbs block weight savings includes the heads).

 

Yeah I've heard of that equation before, but its a rough translation at best. With that MPH of 83 and a 1.97 60 ft. tells me that the top end is there just not the bottom end. So with a few more dollars and some more seat time, 12's will be here shortly. LCA's, air bag and some lower tire pressure will help greatly at the track next time. Then the cam, TC and gears will come over the winter.

Thanks for the compliments guys, and I think the LS1 is the greatest power adder. Also probably the cheapest way to make your stock V6 car 4 seconds faster.

 

I'm not really sure, next time I'll try to get it weighed at the track. The title for the car says it weighed 3000 lbs., but I know that cant be right. There was just too many options on the car for it to be that light. I dunno, we'll see.

 

don't count on the motor not having low end...with a 2.78 gear, you're not going to get off the line too good but the mph will be high. put some 3.73s or 4.10s in there and some slicks on the back and you'll probably see 1.7x 60' and a couple or 3 tenths off the et. mph probably won't change too much.

 

This is the plan for the winter.

I'll be going to the track this weekend for some more seat time, but this is the last weekend of the year so... Next year will be interesting.

 

Your going to need more mph for 12s...

I ran an 8.4 @ 85 or so and that was on a 12.99 pass... I think with a few more things it has a high 12, but for now mid 13s!

 

Not bad, you're turning better MPH than me in the 1/8th, you just need gears to match that high revving LS1

 

Hopefully a deal on a 3000 stall TC will go through, and also on another 10 bolt with 3.73's in it (both really cheap), but it dosent look like I will get any track time this year with those parts. For what I want to do, its gonna take probably the whole winter to get it done so...

Also, it dosent help that our local track has the sticking ability of a ice skating rink. Next year I will for sure be making a trip to the Texas Motorplex.

Meanwhile, its time to replace the cracked oil pan.

Thanx for the replies guys.

 

Yeah, definetly get a stall!!! These motors love 'em.

 

Great times for an out of the box LS1. I love these things! You need to get yourself some heads with that cam. We really need to figure out what to do about longtubes too. With slicks and better gears and a stall your 60 fts will improve nicely. A buddy of mine was hitting 1.4 all day last saturday and he has an M6 with a 383 Speed inc built monster LS1. his torque was so great and he was hooking so well that the driveside rear wheel sheered the axle studs right off... all of them.

My set up should hit 11's easy. I am for sure going to do a bigger cam too. I just want to see how this one goes. I should be set with these Stage 3 heads tho. I cant wait to get to run this thing next year. I need to make sure I finish my drivetrain to handle all the power, my trans and rear need some help. I need to upgrade a few things like cam and exhaust, I need a better intake, most likely an LS6 and the LCA's and panhard I should hit some pretty good numbers. A proper tune will help nicely too.

 

It looks as if I'll need to upgrade my tranny too...http://ls1tech.com/forums/showthread...42#post1880542

This really sux.

Your car should haul some ***** for sure. I think 11's are def. in your future.

If you change over to a tubular K-member and A-arms its no problem to put long tubes in. Yeah I wish some company (Hawks) would do some R&D and get some on the market.

 

have you tried it lately? Still nothing? Have you tried to shift it manually? What happens?

Thats strange, but you could have damaged it. There is a rebuild kit that says it will hold 550hp for the 4L60E. That might be an option if your tranny goes out. Thats what I was thinking of doing. I gotta have an OD tranny.

I would love to change my K-member and A arms... hell I would go wit the rack and pinion if I had the change to do it. I am not sure how strong the tubular K-member is for street and daily driven use. I have heard mixed things on it. I really do want long tubes tho.
