i was hoping to be over 400 but it didn't happen. I am still on stock ECU and no SD

JUst make sure you know the FP black is 84mm inlet which is i believe 3.5" so you will need to buy a coupler for it to put on your leak tester unless you can find one made for the same diameter.

i bought mine from there and its a nice leak tester.


doubt its a leak tho.. if they built car they tested it prior to dyno.. its something else being overlooked. or the cams suck that bad.

 

thx 4 info

 

i said the same thing, there has to be a huge boost leak or the car is veeeery conservative tuned. If you spent all that money the boost leak test should have been done at the shop where they built your car and tuned....i would have never left the shop until things got straighten out or i got what i paid for and thats at least 450whp on 93..

 

Mine has basically the same mods and made 470whp on 93 octane on Buschurs dyno. Something is definitely up. I have buschurs 272s in the car.

 

definately something up timing wise or ya gots a leak. nice setup though!

 

ok well here is the data that something is not right. i agree with previous posts you should go boost leak test and check timing. i hope you find out what is up and get your car running correctly because you a VERY good part combo/build spec.

 

What's the boost level?

 

28 psi

 

we commonly see 430 awhp on the FP red with a stock shorty/head but those are dynojet numbers. If you subtract 13% for BR Mustang numbers you'll be right at 380's. The fp black doesn't do much more for pump gas numbers because like the red, the hotside it small. The cars with built short blocks/heads will do a little better many 450 awhp.

I don't think you're as far off from where you should be as you think. If you were running an aftermarket ecu or filtering out some knock on the stock ecu I'm sure it would go higher. (we don't recommend either)

 

I made higher numbers on the BR dyno - with my 2.0 SB falling apart..

 

stock ecu?

 

Yes. I decided I am going to order BF 272's, AEM EMS and do an e85 tune in spring.

 

My tuner before tuning my car made me get a boost leak test, compresion test, change my spark plugs, checked timing and ect.

 

yes. 27-28ish psi
