Look back in this thread and see who brought up a Z06 originally -- it sure wasn't me (Or even a vette owner for that matter). I don't own either one so I am as impartial as it gets Jeff Quote Link to comment Share on other sites More sharing options...
Guest Hal Posted August 15, 2008 Report Share Posted August 15, 2008 I guess the 8 second stock block Cobra(s) single turbo I'm talking about wouldn't make any 'Vettes cry. Quote Link to comment Share on other sites More sharing options...

kirks5oh Posted August 16, 2008 Report Share Posted August 16, 2008 bow down to the awesome power potential of the terminator with the stock longblock. my plans to go compound boost (twin turbos compounded with my twinscrew blower) are still in order---and i might begin to start collecting parts next spring/summer. i haven't decided whether or not i want to build a 'nuc-proof' bottom end first, or just get the system running first with moderate boost and the stock bottom end. that and a bit of weight loss with the solid rear, and i'll be set. who would ever think a FACTORY STOCK longblock could pound out 800rwhp over and over again and live. there are hundreds of these cars driven daily with 600+rwhp and well over 50k miles Quote Link to comment Share on other sites More sharing options...

kirks5oh Posted August 16, 2008 Report Share Posted August 16, 2008 And the power they make is pretty cheap compared to other cars. this is part of the issue why these cars run so poorly. power is so easy and relatively cheap to make---that owners neglect suspension parts, and light weight parts to drop weight off the car---i'm just as guilty as anyone of this Quote Link to comment Share on other sites More sharing options...

Trouble Maker Posted August 18, 2008 Report Share Posted August 18, 2008 Your car passes my peak hp/tq by 1600rpm. Umm, the only reason it's at that point is because they went WOT at 1500rpms. If they went WOT at idle it would happen at idle+100rpms. Quote Link to comment Share on other sites More sharing options...

Like the 450 hp Ecotec (Solstice GXP) that's completely stock except for a turbo swap? Nice numbers for the Cobra though. That's one of the few mustangs I'd be ok with owning.

"the LSX is much larger than my 4.6 liter" says the ford guy. "put a blower on my LSX motor and see what happens" says the gm guy. up to this point, its been crazy to believe that so many cobras are 600+rwhp with a completely stock longblock. now, with the bigger blowers coming out, many cobras are pushing 700+ rwhp and living reliably without issues. like i said, i'm talking about reliability--plenty are 800rwhp and above and PERHAPS on borrowed time--we'll see--most people who drop the money for big, big blowers or turbos just go the extra mile and get better pistons, rod bolts, and head studs--that's all that you really need. the rods/crank/and block are up for just about anything. hell, i've got 10 hp shy of 600rwhp and have been running the stock headers, stock clutch/tranny/rearend for just about 2 years that being said, i'll be looking hard at the new CTS-V once i start my next job---we'll see if the newer motors (LSA and LS9) respond as well to pulley swaps.

"the LSX is much larger than my 4.6 liter" says the ford guy. "put a blower on my LSX motor and see what happens" says the gm guy. What people should be arguing is BMEP - which factors in torque output and displacement. I used the wrong wording and didn't mean to single you out, but this is one of the first generations of engines from the general that has capable engine & powertrain management, components, design, etc. up to this point, its been crazy to believe that so many cobras are 600+rwhp with a completely stock longblock. now, with the bigger blowers coming out, many cobras are pushing 700+ rwhp and living reliably without issues. like i said, i'm talking about reliability--plenty are 800rwhp and above and PERHAPS on borrowed time--we'll see--most people who drop the money for big, big blowers or turbos just go the extra mile and get better pistons, rod bolts, and head studs--that's all that you really need. the rods/crank/and block are up for just about anything. It would be nice if say the Camaro had an SS option including a derivation of the new FI 8 that was just as competely priced as the Cobra was. hell, i've got 10 hp shy of 600rwhp and have been running the stock headers, stock clutch/tranny/rearend for just about 2 years that being said, i'll be looking hard at the new CTS-V once i start my next job---we'll see if the newer motors (LSA and LS9) respond as well to pulley swaps. To put that into engineering perspective, thats roughly 20bar BMEP. An EvoX, from the factory, is rated at 25.5bar. Some food for thought....

OGRE Posted September 15, 2008 Report Share Posted September 15, 2008 the most common breakdown i hear from 03/04 cobra guys is about breaking pistons. Mainly when they run thier roots type on top end high speed runs. You can't put that much heat into a motor for an extended amount of time, forged or not.

Mainly when they run thier roots type on top end high speed runs. You can't put that much heat into a motor for an extended amount of time, forged or not. They have bad head cooling from the factory which is an easy fix. The reason pistons go is because of the added heat created by a top end run coupled by the tight piston to wall clearences of the forged bottom end. Tight clearences and too much heat (expansion) = boom Quote Link to comment Share on other sites More sharing options...

Tight clearences and too much heat (expansion) = boom yes. ford never imagined (or maybe they did) that TONS of people with cobras would add 120rwhp with a simple pulley intake and exhaust. they figured most cobra owners would be like (most) vette owners--older guys with no desire to hear their pistons slapping in the bores on cold starts because piston-to-wall clearances. so ford made the piston to wall clearance 0.001 to 0.002. the motors that are closer to 0.002 can withstand the heat that comes with multiple back-to-back highway blasts to 140+mph, combined with poor coolant clearance from the back of the driver's side head (by cylinders #7 and 8, which are the most common to expand and scuff the bore). the motors that check in at 0.001 can go boom even at stock levels with improper driving. and the head cooling mod helps limit the possibilty of this happening. i put the head cooling mod on my car when i installed the whipple, but i don't drive my car like an idiot.
