Depends on particular years and models I have heard of some putting just as much or right near the power levels of the M6. When I used to work at brothers Performance LS1.com Members would bring there cars down to dyno there cars and an auto Ws6 put down somewhere like 315 hp and 330 tq on a...

ufortunately it is only the FORD automatic that robs power. The transmission in the LS1's 4L60E will dyno just about as much power as the 6 speeds. Ford needs to do their homework on the auto transmissions. There is a couple of company's that work on these tranny's. I have also seen some GT's...

Well the automatics and the sticks do make different power levels. they are rated almost the same but if you put an auto MACH1 and a 5-speed on a d dyno you will see different results. The auto's dyno about 20-30hp less than the 5-speeds and also do not even runs as strong as the 5-speeds...

This is the First time that Ford has actually used an auto in a high performance vehicle. (Except the Lightning which uses a tranny that is equal to a TH400) they knew ahead of time that there tranny's are weak. so they decided to avoid probs and lower the red-line. I dont know why they use a...

I would have to agree that there are alot of M6 LS1's out there that are driven by average drivers. also A car length is not alot to win by. The LS1 is powerful but so is the MACh1. In my experience the faster LS1's have been the automatics...again because of driver. I have not seen a MACh1...

I really think ford did a good job with the MACH 1 and it was about time...I really do think that stock for stock it is a drivers' race... I have seen them here where I am from go head to head LS1 wins and then the mach wins... I just cant wait till my little notchback is done so I can get...

The new Mach 1's are strong runners but the 5-speeds and the automatics are totally different cars. unlike the LS1's that an auto is = to an M6. The 5-speed in the Mach redlines to about 6800 RPM somewhere in that area and the Automatic is about a thousand less I think...they also use a...

that is great my best time naturally aspirated was 13.7

Well your #'s sound about right 98 cobra's had a better tune on the PC from the factory and if I am not mistaking they had higher compression and also more agressive cam profiles. I dynoed those exact #'s on your first pull to this day. I used to work at Brothers performance and there was a...

Bro there is no worries, I clicked on your link and saw your motor very impressive... what are your mods? your car makes some very impressive numbers. I know that 98's were built a little better than 97's. without the juice on my car I only make 260 horse and around the same torque. with the...

Jeff I had to remove the upper intake because of the EGR fitting and other misc. components that would not allow the valve cover to come out. For the removal of the driver side cover, you will not need to remove the master cylinder, you will need to disconnect the Clutch cable from the quadrant...

hello people's I am changing my valve cover gaskets on my 97 cobra and had to remove the upper intake, I was wondering if anybody here has removed there IMCR plates, and port matched the lower intake? if so please share your experiences and results thanks. any feedback is greatly appreciated. I...

4.10 or 4.30 gears and his car will feel like a totally different car...

that makes no sense whatsoever. dropping the K memeber for an Opti in an LS1 to get to the optispark to change a plug. :lol: Please man do some research first. Like someone already stated there is no opti spark on an LS1 and also on the LT1's you dont need to remove the opti to replace a plug...

a blown LS1 would of blown your Mach1 and your modded cobra away. No questions asked and hands down. I am from California riverside to be exact and most mach's and older cobra;s get owned by LS1's around here. average time for mach's around here is 13.5's and what are you talking about LS1's...

thanks people for all the response. trip out I ended up going with a turbo setup from precision turbo. The kit costs around 4000.00 dollars and comes with everything, 67MM turbo all tubing, headers, intercooler and will make about 550-850 RWHP depending on boost levels.

Hey guys I have an 89 mustang 347 forged stroker with AFR 205's and I am needing advice on which kit to buy for my setup any info would be greatly appreciated. thanks

Well is it not the same concept as using an aftermarket on opposed to a ported one? also I see that you dont have the IMCR plates did you notice anything after removing them?

I was wondering if anybody has ported there stock maf meter? I have heard about it being done just wondering if anybody has any links to this or info, I was also considering removing my IMCR's let me know what you guys think. My current setup: 1997 cobra 100 shot ZEX 4.10 gears h-pipe...

Your TB will continue to do the weird idle because of the lack of quality in a BBK product. BBK's TB has an offset Shaft compared to the original, to compensate for this BBK drilled the TPS holes at an offset angle, very very poor design. This has caused many weird problems such as: weird...
