    Long Tubes a waste on N/A cars.

    I hate it when that happens. You know what you want to say but can't pronounce it. :D Well my point it would almost make more sense to put the money into cams. You pretty much have to drop the K member to get the LTs in. There are better ways to spend your money that will give as much power if...

    Long Tubes a waste on N/A cars.

    I hate to stick up for the guy but it is a known fact that the manifolds are good up to about 340 rwhp. When I say good I'm talkin about not a restriction. Now the gains yall are seeing is because of better exhaust scavenging not necessarily lack of flow on the part of the stock stuff...

    Mach 1 the mach 1`s competition?? pics!

    I think it will be quick. Its just a couple of boltons away from twelves. And Bolt ons work on LS1s like they work on 03 Cobras. Don't get started on what happens with heads cams and intake work too. Its also easier to increase the displacement too. Do not forget what 30 years of short block...

    Pro-M says my MAF is calibrated for a '93 Cobra computer, will it be fine on my A9L?

    36 at idle is good from what I know. Pro-m is the best aftermarket stuff you can get but unfortunately its still garbage. The shorty pro-m is the best. I beleive 2001 blacksnake may have what your looking for I don't know for sure. I'll check with him tomorrow for you. Where in MA are you from...

    Pro-M says my MAF is calibrated for a '93 Cobra computer, will it be fine on my A9L?

    My maf does that and it is calibrated.I've had to send mine back to pro-m twice and its still not right. The fact of the matter is that the ford maf is 10X better than any aftermarket maf. I hate to say it because tha ford stuff is only so big. C&L is worse than Pro-M. Mafs just suck. I'm about...

    I don't wanna talk trash but Pro-M probably makes half their money off of recals. They know they are about the only people out there in that business. I suggest you get your A/F checked because if your meter is off you won't be able to say its working fine. Your car will not even remotely act...

    Mach 1 the mach 1`s competition?? pics!

    I am almost certain its an Auto. The man can drive his Formula is the second fastest full interiored bolt on LS1 as well. oogtdude I think he was talking about the GTO having coil on plugs.

    I went 13.2, what mods should I do to finally hit 12s?

    I have to agree with him. Suspension is a major factor in these cars. Power means nothing if you can't put all of it down. But the Machs have a very soft and springy suspension. Part of the reason why LS1 cars are so nasty at the track is because of their suspension. Look at my time in the sig...

    I went 13.2, what mods should I do to finally hit 12s?

    Cause two chambers only flow like 217 CFM where Magnaflow Bassani and others flow about 360 CFM. My tuner told me with a decent Catback my numbers would be well over 400rwhp but since I have a frankensteined 2.25" 2 chamber set up on mine it only made 396rwhp.

    I went 13.2, what mods should I do to finally hit 12s?

    Gears will keep you in the power band much better. I was stuck in the 13's until my gear swap. It planted me directly in the twelves. Get rid of the flows for Magnaflows. And do not use anything less than 3.73. 4.10s are better.

    I cant wait for the first mistake. They are going to take it back to the dealer and tell them to fix it. All they will see is GT.

    Mach 1 the mach 1`s competition?? pics!

    And GM has been known to blow its #'s out of proportion. And what do you think the Mach 1 is? its not SVT its regular production Ford. Their answer is doing the same speeds as a 346 LS1 with a 281 Mod Motor

    They even are stealing the three heater and ac control knobs from Ford. If you want Retro looks buy a Ford if you want retro parts buy a GM.

    Spec Stage 2 vs. King Cobra clutch

    My clutch gave me ET because the stock was slipping pretty baddly. I didn't realize how badly until I switched it went from 13.0s to 12.8s. I have a king cobra and its working fine I try to go to the track at least once a month. I will say I've only had it since September. But it works great. I...

    Exhausting question.

    I know its been played out but I need to find a good exhaust for my car. ITs a 2K GT its supercharged aftercooled and powerpiped making 12#'s of boost. Well the problem is I need a much better exhaust than it has. It has Stock manifolds, Magnaflow 2.5" X pipe, and a meineke butcher flowmaster...
