Trick Flow "Street" vs. Cobra. Which Is Better?

01-17-2001, 06:17 PM

Ok, here is the deal:

I misread his post, I had the "Track" Heat Intake, a step up from the "Street". However both intakes are very similar.

My car was running the GT40.
ET was 11.70 at 114mph.

The car was never on a dyno with the GT40 intake.

Now, I must clarify that with the GT40 the car pulled strong till 6200, which also was the RPM that I crossed the Finished line at in 3rd Gear (C4 trans).

Anyway, I put a call into Trick FLow and they recommended the "Track" Series. So I ordered it and had the upper and lower match ported to my Street Heat Alum. Heads. So far so good.....that is till I went to the Track.

I clicked off a 11.90 at 111mph, three times in a row. Not to mention the air was very cool with low humidity. This was in April I believe. Anyway, a guy had a mobile Dyno at the Track so I put the car on it and this are the results:

Torque 432
HP 277

Wow

that sucks.

As you can see my car ran better with the GT40.

A week later I decided to try the Downs Ford box upper and GT40 lower on the Car. I went to the Track and WOW look what happens:

ET 11.55
MPH 115

Hmmm, now you tell me?
Looks like the Box upper is a keeper.
Also, I have yet to Dyno the motor, but a few calculations will tell you that to drop from 11.90 to 11.55 and gain 4mph, I definitly picked up across the board.

Combo:

75mm TB, 77mm Mass, Lunati Cam, 3900stall, C4, 347ci, 1.7rr, 4.10gears, 30lb inj, 190lb pump.
