Anyone dyno less than 400rwhp with JUST a CAI and catback?

[Sickness23]

friends made 345 stock, 377 cold air, 395 w/ xpipe but with 13.5 a/f with faulty 02 sensor..........redyno soon, should be easy 400 rwhp with no other changes

I will be dynoing in about 2 weeks with a K&N and Magnaflow Catback. I'll let you know what I get.

I'm hoping I get below 400 so I have an excuse to add a pully.

Back in May, with 24000m on the car, I dynoed 388HP and 387 tq. Same day, same dyno, 2 other Cobras did 401, 377 (yes, identical). My AF was very rich. The tech said maybe colder plugs would get me higher.
Only mods were Stinger and Densecharger.
Haven't yet dynoed the new car.

421 RWHP & 391 RWTQ (DynoJet)

Dynomax Ultraflow Cat-back & Pro-M Air Filter (open element, no shielding).

I have not dynoed it with my K&N AirCharger yet.

403/371 with just magnaflow catback and JLP ram air!!

I pulled 412 RWHP with just the K&N FIPK and stock exhaust set up!!! I have the proof and a witness member of this site. UNBELEAVABLE, but so true!!!!

398/365 with ONLY K&N FIPK, Just added some Flowmaster weld ins and we'll see how she does, shouldn't have a problem getting the extra 2hp with the flows on there now!!

K&N and Magnaflow cat back, pulled 413rwhp & 375rwtq SAE. Uncorrected was 430rwhp. I'm happy for now. Will dyno again next week with my pulley and tune.

The first trip to the dyno was with the Magnaflow cb only it was 376rwhp/362rwtq. Then I put on my K&N FIPK and Magnaflow x-pipe w/ cats and got 415rwhp/385rwtq.

I'm getting dynoed on the 23rd. After reading this thread I really hope I'll hit 400hp.

Voted No

Just hit the dyno yesterday; a few weeks after putting on the Steeda CB = 412/400

Here's the graph

Edit: Tune from James + tailpipe sniffer. A/F a little off on the lean side but am investigating reliability of the dyno A/F data. We had a guy run his wideband at the same time and the results don't compare well.

 

[DitchTehFish]

Thanks for the responses guys. Those of you who dyno'ed 400+, was your car tuned? Everyone, did you get a tailpipe A/F ratio reading, or through the o2 bung?

404hp and 396 torq with 8" anderson powerstack and magnaflow catback. Good torque curve but hp flattened at 6K rpm

 

[Chris_H]

With just an open conical K&N I put down 412/394 with 5800 miles on the car.

 

[jason1320]

402 HP here....:rockon:

 

[Oh Three Cobra]

Haven't dynoed yet, but I got a Magnaflow catback on the car now and a JLT intake comming next week. What kind of dynos are you guys using? That makes a significant difference. For example, mustang dynos tend to read lower than a dynojet.

 

[jason1320]

Mine was at Kaufman's (spelling?) in PA. I believe it was a DynoJet. :??:
