I just mentioned the Z06 because he said he was racing one. I've seen the new RX-8's and they weren't impressive. 4 doors, 14-15 second ET's, no turbos, don't handle as well as FD, etc...So what happened?

They are underrated.. A friend here in MSR (link) name Uncle Meat on the boards has one with just intake, exaust, and a short shifter and got 425rwhp! Stock pulley also! One bad bitch of a car.. check out the dyno vid on the forums.. its on there somewhere..

LOL it doesn't. I saw a yellow one at the local autocross and that thing is such a pig around corners. After plowing all over the place the driver got frustrated and gassed it, and went spinning in circles knocking cones in all directions.

Hello all. My cousin boosts around Dallas, TX in a '93 R-1 RX-7. I hail from Los Angeles, CA. Used to boost around town in a '91 HKS Stage IV MR2-Turbo. Currently troll the streets in a BPU '03 Cobra. Allow me to clarify some points. HP numbers of the '03 Cobras are factory underrated. 390 BHP, 360-370 RWHP SAE. Assuming a standard 15% parasitic drivetrain loss, that would equate to approximately 425 BHP. Quarter-mile times for a stock '03 range between low-13's and high-12's. The problem is traction and IRS wheelhop. A set of drag radials and a few practice runs should net high-to-mid-12's. The '03 naturally understeers. Correction involves feathering the throttle to swing the rear out. Yes, it is a pig. Provided that the driver is familiar with inducing traction through weight distribituion, the '03 is surprisingly neutral in and out of corners. The stop in production was relating to faulty cylinder heads, which the '03 Cobra shares with the '03 Lincoln Aviator. ETs and MPH depend on track conditions, elevations, and most importantly, octane ratings. Numbers from the East Coast will generally be higher due to a cooler ambient temperatures and 93 octane. The advance in lead can net upwards of 10 RWHP SAE. Basic bolt-ons include:
Intake: Generally a cone filter attached to the mass air flow (MAF) sensor. Approximately 1800 CFM.
Exhaust: Crossover piping and cat-back system. Aside from long tube PEMs, '03 Cobra-specific headers are a couple of weeks away from being publicly available.
Pulley: A swap down from the stock 3.65" upper pulley. Generally 3.10, 2.93 or 2.80".
Chip: Aftermarket chip attached to the ECU. Regulates fuel, timing and a plethora of miscellaneous options.
A BPU '03 with the above listed mods - sans headers, w/ 3.10" pulley - should net 440 RWHP SAE, 440 RWTQ SAE with a good tune. That is what I am putting down. Conservatively. A competent driver should be able to put up mid-to-low-12's on street tires. A 2.80" should see upwards of 460/475, respectively. A competent driver should be able to put up low-12's on street tires. I hesitate to mention high-11's as again, traction is the enemy. Detonation is an issue, although less so than with the RX-7. A relatively rich tune of 11:6:1-11:8-1 and a set of properly gapped NGK TR6s or Denso Iridiums wards off the potential for blown engines. BTW, I was recently pulled by an R-1 when I was @ 420 RWP, 420 RWTQ. My defense is that I was in 4th on a 6-gear while he was 4th on a 5-gear. He probably would have still pulled me, although not nearly by as much. See <http://www.svtperformance.com/forums/showt...=&postid=329828> Hope this helps.

So, you lost to an FD with 420rwhp? I wonder what his mods were.. What does it make a difference if it's a 6 speed (cobra) vs. a 5 speed (FD)? When both of you were in the same gear.. The link never came up for me.. but it's probably just my dumbass computer..

I had 420 RWHP, 420 RWTQ at the time. He had 416 RWHP, 319 RWTQ.

Not sure if it was Cosmo-powered, but the Garret T04 certainly stood out. Tuned by XS Engineering, Hungtington Beach <http://xs-engineering.com/>, one of the top import tuning shops in SoCal.

It is all about gear ratios. Generally speaking, 3rd gear in a 6-speed is the equivalent of 4th gear in a 5-speed. 3rd in an '03 runs out at about 110 MPH. That said, I was not in my pulling gear during the run. A kill is a kill, nonetheless. Kudos to the R-1.

No. SVTPerformance is currently down for maintenance.
