Tell me this guy is wronglil305gta 09-07-2005, 12:55 PM This guy is a very reputable mechaninc and apretty good friend. He claims that my brother's lt1 with a y-pipe, no cat, flowmaster exhaust, k&n fipk, centerforce clutch and 4.10's will pull on my ls1 with 3.73's, slp heavy duty posi diff, shift kit, fresh tune up, lca's, and sfc's. If he is right what do I need to put a car or two on the lt1? I got a few hundred bucks left after this rear end rebuild....lid, ssra, catback, tq arm, panhard...in what order? timothy_5326 09-07-2005, 01:13 PM well lets face it.....with a six speed and 4.10's, he will probably pull you out of the hole. the problem will be running him down. sounds like you need some juice....a 100 shot should do. :D SteveC 09-07-2005, 02:43 PM This guy is a very reputable mechaninc and apretty good friend.

He is correct, he wil pull you out of the hole, however the LT1 is known to fall on its face around 4K RPM's, you should easily be able to run him down on a quarter mile. After you do this, make sure to ask him "If all your brake lights are working" :D SteveC :) blind527 09-07-2005, 02:53 PM He is correct, he wil pull you out of the hole, however the LT1 is known to fall on its face around 4K RPM's, you should easily be able to run him down on a quarter mile.

Might be pretty close though. He is correct, he wil pull you out of the hole, however the LT1 is known to fall on its face around 4K RPM's, you should easily be able to run him down on a quarter mile. 4k? It's an LT1, not an L98. It should pull pretty good until about 5000-5200rpms. SSpdDmon 09-07-2005, 10:20 PM http://www.ls1sounds.com/Borla/borla-open_stock-manifolds_ORY_track_inside.wmv That's what it will look like. That LT1 had 4.10's and a Hypertech tune for sure (may have had cold-air and cat-back too). Mine (left lane) had a lid, Granatelli MAF, lca's, and Borla cat-back. BigZ28 09-08-2005, 10:23 AM I would look into the TCI converters. A 3500 should net you about .5 drop in the 1/4. Just heard back the other day from a customer that dropped just over .6 at the track after installing his TCI 3500. It makes a great street/strip converter. We have them for $524.99(+shipping). Brian robvas 09-08-2005, 10:54 AM I'll second the TCI converter. Friend of mine with a 2.73 car lost something like .7 at the track. If you have an LS1, you will win. Easy. 00Z28SS 09-08-2005, 04:53 PM well lets face it.....with a six speed and 4.10's, he will probably pull you out of the hole. the problem will be running him down. sounds like you need some juice....a 100 shot should do. :D Juice would be any overkill....but is there really an overkill :D | ||
