you ran it a dragway 42 didn't you? i was there. car looks really clean dude

big shot dyno is a great shop as far as ive heard.

Blown Spring GT · May 21, 2009

Yes that was me. The car is very clean and on 30k on the car makes it a better deal.

i had my car out there but i didn't run it. it was my first time being a d42. i think i will be running my 01 gt next week.

The 99/01 Cobra and Mach 1 have better heads/intake than a B head Cobra(96-98) and the Mach has a better powerband than the 99/01 Cobra due to the different cams. Both cars make more power in stock form than a B head Cobra.

Sounds like I have my work cut out to make 300hp or I should say my wallet has its work cut out. I have to stay in the hp race.

slow. Need to get that 60' under control.

On what planet is 13.7 slow for a stock '96-'98 Cobra? I agree there's more left on the table with that 60ft, but 13.7 as a base run is way better than average....especially in a car with the stock 3.27 gears.

Blown Spring GT · May 21, 2009

I'm not saying 13.7 is slow but my old 00 2v gt with bolt ons went 13.4 at 103moph. I was asking if that is a good time for a stock 96 Cobra. I think the car has way more left in her. The car is soooo hard to launch. It is eather spin or bog. It realy needs some gears in the rear end.

A bolt on 2v is going to be faster than a stock 96-98 4V with drivers being equal. Your time is very good for a stock 4V despite what four six said.

Blown Spring GT · May 21, 2009

My bolt on 2v only put down 263hp and 304tq with every bolt except headers. I am thinking My Cobra is puting down around 260 stock. The only major dif. being wheels and tires. My cobra has 18" rims with bald tires on them. I am very happy with the rt and mph my car laid down.

blackfang · May 21, 2009

Yes and your 2V had more rwtq(many do in stock form too) than a stock 4V which is why it tends to get down the 1/4 quicker. The B head 4V has less torque in stock form and the same rwhp as your old 2V.
However, the 4V relies on the higher breathing hp to get the job done. That is why the C head Cobra ran 13.4-13.5's in stock form as they had more rwtq and rwhp. In a way Torque= how much work and engine can do and HP= how fast it can do it.

Gearbanger 101 · May 21, 2009

Its not necessarily that the ealy 4V's made less torque that the later PI headed 2V's (they make slightly more actually) its that said torque comes on somewhat later in the power band by comparison. A few guys have experimented with modifying the IMRC motors to allow the plates to open a little later on in the power band that they're set up from the factory (approx 4,000-4,200RPM). This is said to improve torque, throttle response and in town fuel economy greatly accross the board with the early B-headed DOHC engines.

I might consider looking into that before going too drastic with the rear gears. Especially if this Mustang is going to spend any time on the highway and is expected to retain any sort of fuel economy.

Blown Spring GT · May 21, 2009

How do you adjust them. Do I have to use my VCM and change the imrc motor settings?

svtmust97 · May 21, 2009

I made 305hp without cats and 300hp with cats at the rear wheel. On my 97 Cobra. The set-up I have are bbk Lt, O/R H-pipes, pullies with timing adj. pro-m 80, 62 tb, Accel coil pack. MSD dis-4 w tach ad. 300hp with cats and X-pipes and a good tune-up.

Blown Spring GT · May 22, 2009

I went to see Keith at Big Shot Dyno last night. I made a pull and the Cobra laid down 282.1rwhp and 275.3rwtq. Keith said that was very strong for a filter and cat back exhaust.
