BBR Testing with Ford Racing Intake Manifold

[Dillon Dollar]

I see nothing wrong with your numbers. What pistons/compression?

Is that built engine broken in? How many miles?

Chris wants to see the car put down 390+ to the tires when i said it made 360 those were peak numbers i actualy lost power in the mid range compared to my old set up (BBR Stage 1's) and yeah my compression is a tick lower but not much at all only enought for a like 5 or so hp difference, and i do realize that it is hot in florida, he thinks that the old gas or 02 censors are my problem.....what do ya'll thing

Normally a Stage 2 heads + cam car make 375-390 rwhp i was expecting 360-370 with out the manifold, and with it hopefully 390 to low 400's

 

[Dillon Dollar]

^^^ good point. A built engine if not broken in won't just make power right away. Needs a bit of time for everything to settle and seal first

The motor has right under 10,000 miles on it

What we dont understang is why I only picked up a little under 20 RWHP with the Cam swap and addition of the new manifolld...it should be more like 40 or more

Who said that? 20rwhp sounds about right another 10rwhp going from stage 1 to 2 and 10 for the manifold.

but that doesnt explain the massive mid range loss i had, i mean like i said chris has never had a mustang with the stage 2's make less than 375 and thas with out manifold...there is some guy with hot rod cams and no headwork with the manfiold that put dowm 380 ... the whole matter is just depressing chris's exact words were "something is wrong it didnt make the power it was supposed to but i will fix it dillon" i guess im justa little frustated i mean iv been with out my pony since June 12

I want my car put down 600rwhp, whats your point? LOL

Of course you lost low to mid range! a stage 2 cam builds more peak hp while sacrificing idle and midrange power/tq compare to a stage 1. That manifold on a n/a car also looses down low a bit.

Again what pistons/compression? Im running 9:1 and it cost me 20peak hp and some loss downlow.


Seems you are whishful thinking, and bbr got you hyped up, everycar is different man, slap the same mods on 2 different cars and there will be discrepancies everytime. A stage 2 head/cam full bolt on car is a 350-375hp car depending on the setup. It's very rare to see any higher that. In stock displacement n/a trim. Maybe if you had a stroker and stock compresison or higher, i could see 375rwhp+.

And yes the heat is hurting you for sure.

Take it to the track and see how she runs/traps!

Good luck!

When i said it lost mid range the loss was extremely bad i think it actually dipped down into the 200's, and i believe my compression is just like :1 lower than stock....

Thanks for all your suggestions thou i appreciate the tech talk

 

[JeremyH]

No prob, If you can tell me which pistons you got i can tell you what your compression is for sure.

Have they done a compression/leak down test?

If you can get some graphs of whats going on there are plently of guys here that can give you advice/pointers on what the issue may be.

Chris has a video of his car making 380.1 rwhp and it was not a stroker or anything like that, and there is another video with aggressive tuning and race fuel he made 406 i believe....and the numbers i put down he told me it was with really agressive tuning...whatever the problem is it was big enough that they didnt ship my car back to me 2 almost 3 weeks ago

 

[Dillon Dollar]

Man i would have to find the specs on all the parts when i did the motor build last year beacuse a comp mutha thumpr cam locked my car up lol, iv definetly not had the best of luck with my stang...Ill see if i can dig them up tonight and post them

Sweet man, yeah the shop cars always tend to make more power than the avergae guys as they do things they dont tell you about... Ive seen it time and time again.

Well good luck getting it sorted out, the midrange thing does seem like an issue. Hopefully they can figure it out! But dont be bummed if you only make 360-375rwhp those are repectable numbers for your mods.

Thanks man ill keep everyone posted on the numbers an such, im just ready to blow the car ill probably be going with the D1SC this summer, i was going to go turbo but it will be a pain on my car with the cervinis side exhaust and such

Sweet, she will make some seriously power at low boost with a d1sc on your car. Im guessing 575+ at 10-11psi.

I made 332rwhp n/a all bolt-ons, stock heads stage 2 cams after i built the block and dropped to 9:1 compression. Im pushing 540rwhp at 12psi, possibly closer to 560-570 with the frpp intake manifold, i have to get back to the dyno and get tuned frst. The day i went on the rollers was 110 degress and it was lean/pulling timing and let out at 4,000 rpms, at 4k i was up 32rwhp and 21rwtq only change was the frpp manifold.

I remember reading your post on that considering the heat i was really impressed....what kind of power do you think i can hold considering everything is forged except the crankshaft ??

 

[JeremyH]

Crankshaft is not a weak point, just keep it under 7,000 rpms since the stock cast crank is not counterbalanced. What ever your rods/pistons are rated too is your limit. Did you upgrade your oil pump gears?

Yeah last year when a threw a rod i scrapped everything and went with all new parts except the crank but i did purchase it brand new and idk if BBR counterbalanced it or not, but i remember going with the best of the best stuff at the time just couldn afford to stroke it or buy the kellog forged steel crank
