FRPP Intake Manifold with Turbo Results

[Irishman]

Can't wait either.

 

[07 s197]

got a little sneak peak of a pull. with a pull up to 4500 before having to let out it was already up 30whp

 

[yellowjohn1]

That's very promising. You have to back out because of A/F ratio?

 

[killermustang]

the only reason i would go w/ C&L and i quote from an article in the september 2010 muscle mustang & fast fords (the gasket is designed to bleed off the boost and re-seal as the boost level drops) this is apperently at 30psi. good luck with your build

Yeah it was running too lean for comfort 12.6-7 ish north of 4500 had to let up and add some fuel. Didnt get to see the rewards of a full pull though since it was 110 degrees in the shop and iats were 130ish. All the runs were pulling timing and just go flat will have some more info and pics in a little bit. I think i lost 20lbs sweating today.

Was also throwing the iat hi temp code.

Didnt get to to the full testing i wanted, but still some promising results to come.

 

[JeremyH]

So got there at noon. Let it cool down. Did the baselines. It was 99 degrees 38% humidity. eboost2 showed exactly 12.0 lbs of boost and water temp was at 190-200 at the end of the runs. Every pull pulled timing up top due to the heat. And every other pull would throw the iat hi temp code.
Baselines averaged around 486-490rhwp 510-520rwtq.

Then swapped the intakes.

 

[JeremyH]

About an hour and ahalf later started her up to do the first pull with the new manifold. Let the car warm up to 180 first. By this time we were seeing 107-110 degress and 25% humidty in the shop.

Just a nasty hot, bad day for doing the testing damn it!, anyways...

Mike had to let out as it was a little too lean past 4K rpms. You can still see the low-end gains and really started to see the difference from 3800+. Blue is baseine red is frpp intake. Even so you can see peak gains of 32rhp and 21rwtq.

Added some wot fuel and pulled again about 10 mins later. It pulled timing again so its hard to judge what the gains are really going to be past 4500rpm which sucked. Did another run just to see. Iats were 128, iat hi temp code....
Decided it was too hot and called it a day so no ba5000 and no upping boost for now.
Not a huge difference in peak gains since it occure as timing was being pulled put still very noticeable difference from stock manifold even below 4500!
(2 blue lines are baslines and green and red lines are frpp manifold)

 

[JeremyH]

Oh and btw the steeda strut tower brace doesnt clear the frpp manifold. Its gonna need 1/8 inch spacers on each side.

 

[GrnBullitt08]

Very nice. I was extremely hot here today as well... 102. I was miserable working on my car and had to call it a early day around 2-3. Just couldn't take it anymore. Nice numbers despite the high heat. Cant wait to see the results once the temps are more reasonable.

 

[JeremyH]

On an 80 degree day the same tune on the stock manifold made 539rwhp and 546rwtq at 12psi/16 degrees timing. Next chance we get on a comparable temp day plan to do a few pulls, overlay the graphs and see how the frpp intake compares throughout the rpm range. Then swap to the ba5000 retune and up the boost!
All in all not the best day but did get a glimpse of how the manifold is going to do with the turbo. I am happy with it for sure! Btw car feels more solid/smooth through idle, throttle tip in and decel.

 

[Bullitt3478]

Congrats on the intake,and the results.

[lostsoul]

damn. it almost makes up for the heat soak. It was damn hot when I did mine too.. maybe Gore is right.. we're all F'ed.. haha

ohh.. I cant remember if someone said it.. would the gt500 TB go on it without doing the file thing on the holes?

 

[JeremyH]

Yeah it almost does until it starts pulling timing, argg....

Since my bkk tb went on just like the stock manifold i would assume the gt500 still needs an adaptor, or modifed holes.

Have you thought of meth? Run 3 nozzles, 1 before the turbo with a very small jet so it evaporates in the compressor and cools IATs down and pick up 1 -2 psi depending on boost, and two nozzles before the throttle body, preferrable before the IAT sensor. Run 50/50 and turn the wick up with the tune you have now. You should pick up a point on the A/F so it will put you in 11.2 range.
Since your tune is set to pull timing at 130* it will act as a fail safe.

I have considered it... have a few other things i need to do first though. Like add a second fpdm switch to ba5000 maf retune etc. I think i can run the meth off one of the aux lines on my eboost2 as well.. How about a small jet in front of the turbo, small jet in front of the maf/iat and larger jet infront of the tb? Would that work? Or is bad to spray the maf. Im guessing its best to relocate the iat sensor closer to the manifold or seperate from the maf when doing meth.

 

[retfr8flyr]

I would relocate the IAT sensor inside the manifold and just run one jet before the T/B but after the MAF.

I like to fact to run 1 smaller jet to cool the charge down before the intercooler through the compressor. Small enough to evaporate in it. Then run either 1 or 2 (2 gives better atomization, better charge cooling) before the thottle body but after the MAF. If you could relocate yours in the intake then better, I relocated mine 1 ft before the throttle body since mine is still draw through. We installed a kit on a 04 cobra that picked up 40whp from the meth kit with 93octane than with C16 alone. Same timing and same A/F. IATs dropped from 187* to 120s giving 2.2 psi gain from the nozzle before the turbo. This is using 50/50 meth.
I was never a firm believer till I seen what happened with the cobra and how much money it can save from switching to Meth. Make sure the tune is set to pull timing in case of a failure.

Thanks for advice guys
