I am in the process of removing my smop set up and using the new belt from the tech article. One of my buddies told me that on race day at the track (Fridays), he uses a diffrent belt that deletes the power sterring pump. just like the pic in the article.
Just wondering if any one has tried that? He says that he notices a diff, the only thing is that he drives a mustang, so the belf is not the same. Any one dones this? Results? P/N?

 

Yeah, a friend of mine does that on his 98 Camaro. Just has a shorter belt that bypasses the power steering. He is running 11s without even touching the motor.

I tried running with no power steering in my old 85 a few years back. With v-belts it was easy to take out of the loop. That car was reasonably consistent, and i never saw any real gains from it.

If you want to give it a try, go for it, but don't expect much. Especially if you're running fat street tires vs. skinnies, the extra 4 hp don't make up for fighting to get the car staged straight to me.

 

Just wondering if anyone has the part # to the pic that I posted, it would be of great help and I could give every one the results.

 

Hey Tim, does your buddy have a webiste or a list of his mods. 11s on a stock LS1 is hard to believe if its N/A. Does he have NOS?

 

11s is not that hard to believe on a stock LS1 with strictly bolt ons. More than a few guys were doing it. I'm not sure what the bolt-on record eventually got set at though but i know it was getting pushed deep into the 11s as of last year sometime.

 

He has done nothing to the motor. All he has done are headers, race mufflers, shift kit, vigilante converter, et streets, suspension mods, air intake mods and a LOT of weight loss.

11s are no joke on an ls1. i just recently sold my 01 gt. at the time when i was spraying, all i had was 4.10 gears, off road pipe, short shifter, and drag radials, and the 150 shot of n2o, and i was running 12.3s. i got beat by an ls1 that night that ran an 11.9 with just a lid, programmer, thermostat, full exhaust, and drag radials as well. my buddy has a bone stock 98 ls1 a4 that runs consistant 13.4s.

 

I love my v-belt. I can get rid of the smog pump, air conditioning and power steering with my pocket knife.

It seems like a good idea, just don't expect to brake to hard or turn much.

 

Impressive, but not what i would call "stock".

 

If the engine has never been opened, the engine is most definitely stock by any racer's definition. And none of that stuff is in the engine.

As for the car itself being stock, he never said it was, and none of us meant to imply that. But exhaust, lid, converter, traction and weight reduction are absolutely "bolt-ons only", which as far as i can tell is what we were all talking about.

 

Stock is a relative term. If you never touched the car, its stock, if you touched it, its not. Last time I checked, headers, CAI, Chip, missing body parts and spray are not dealer options, so they are not STOCK. Now is an LS1 running 11's without cracking the motor open impressive, hell yes it is. Its just not stock.

I think he meant that it was a bolt on car running 11's. If it doesn't touch oil, then it's a bolt on! Headers, convertor/clutch, headers, gears, rear end, suspension mods, air intake, intake manifold, weight loss, sticky tires, skinny fronts, running a short belt......all very easy mods that together will get an LS1 into the 11's.

BTW, I've seen some cars get between a tenth and two tenths by running the short belt on LS1's.

Does somebody wanna show me where I said that it was stock? Thanks Ed & Nasty for backing me up on what I DID say.

Thanks
Tim

 

If this guy is running 11's on a stock LS1(and I agree it is stock even with bolt ons) I would like to see all of his mods and what kind of programming changes he has done. A friend of mine has a '98 TA and he has done about every bolt on we could think of and he is having problems running 12's. Get this... He ran 13.2 with a 3000stall converter and drags. He has sinces added full exhaust, headers, went from 2.73 gears to 3.42 gears. At the track last Friday, he ran 13.06. Something doesn't add up. We think he has some programming issues to work out. It is amazing that he got nothing from all the mods that have been done.

 

Still wondering if anyone has tried at the track? If so any results?
Still wondering about length and possible part #.

 

There is definately something wrong there, I know someone that went 12.9's with just a muffler and a lid, on street tires. Most don't run that quick stock, but with a few bolt ons, 12's should be EASY for an LS1.

 

My buddy's Grandmother has an '02 WS6 and we put a lid and a ported MAF on it and the car went 13.89 on street tires. It's an M6 though. Check out easternfbody.com and search posts by a guy names 02bluefirehawk. He's been mid 11's with bolt ons. Headers, lid, 3600 convertor, slicks, LS6 intake, cutout, and I think 3.73s. He's not the only one. There's problalby a dozen or so guys ( just from our shop!) that are into the 11's with bolt ons.

 

I am the guy the jfreeman74 is referring to. Something is seriously wrong ever since installing the Hooker LT and 3.42's. I have gained zero with both mods. At the dyno, the car gained 31.7rwhp from full exhaust and the AFR was 13.2 across the board with zero knock. That should have translated to a nice gain at the track. I will be Autotaping tha car this weeked to dial in the LTrims, but find it hard to believe this is the sole problem. Before these two mods, I ran 12.87sec with a 1.88 60ft. Even since the installing the 3.42's, the car feel more torquey. Now, that should have resulted in better times and gains were zero. The 1/8 and 1/4 mile traps were the same befroe and after.

 

Try looping a string around all of your acc. that you want to turn. Then take the string off and measure it. From there, start to look for the correct length.

 

Something seems wrong with your car. Are you farmiliar with LS1 edit? Your car may need to be dyno tuned with edit to get it to run right. Autotap should point you in the right direction. I work at an LS1 shop in maryland, I'm sure we can help you out. Check you PM's.
