2003 Cobra
The dyno was done on two different days, but it was the same dyno. But the d/a was around 200 ft of each other and both runs are SAE corrected.

My stock run, I did have a kandn filter. But I gained 4whp from the CAI at least on that day and lost some torque. Was expecting more, but Tucker said only way to do a before and after is on the same day.
Comparing my runs with last time, I noticed one huge thing. HEat soak doesn't happen nearly as quick. On my third run with the stock intake, I was losing about 10whp the most I lost this time was about 3.5whp.

It also looks great inside the engine bay. ANd you can feel that it doesn't get quite as hot as others like the BBK.

EDIT:
Looks like it doesn't like photobucket.

I put down 366whp stock, and put down 370 with the intake.

EDIT: I'll say the same thing here as I did on svtp.. smiley included.. lol

Should've given you more than 5RWHP. Maybe it needs a tune

Also, is it just me or does anyone else think that chart looks way too choppy?

Are you having any belt slip issues? If so, that could also explain the minimalistic gains..[/align][/align][/align]

belt slip really only occurs with pullied cobras... however you should be seeing more then 5 rwhp from an intake... Did you get a tune when you intalled the intake?

oh and btw... nice numbers!!

Ubergeist

No I did not get a tune. I didn't think it was needed.

Anytime you change the airflow in these cars it is necessary. My advice, pulley it and tune it. As if you do want to pulley it in the future, you would need a retune - the pulley is all of 80 bucks.

What was your A/F? It doesn't show on the dyno???

many times the choppy graph indicates a need to add timing.

The JLT shines better after the pulley swap.

Take note that he already had a K&N Filter or CAI installed so gaining power over another intake is respectable.I will be ordering my JLT soon enough.
