FP Race Mani, Actual Test Data?

[Artago]

It's nice to see the results. I have a V-Trim which takes a second to spool. So it's nice to have the help of a FP mani. Also, the HP and torque gains are nice.

 

[TSIMonsteR]

Well, If I ever get a response from FP on my questions for the group buy I will be getting one. I am currently running a non-ported, possible warped 2g mani. I'll post the DSMLogs back to back to help get some data out there.

 

[JWoodley]

Email sent. I'd like to get some group buy pricing on the 4" intake as well. Is this possible?

 

[fwdeclipse]

Well since the 4" intake is not really a new item and it is already I think fairly priced at 70 bucks I doubt they will be doing that. My new manifold will be here on monday and I will do a datalog before I take off my evo gt manifold, then will do another log with my new fp manifold installed.

Tsi monster what questions did you exactly have, when I talked to aneile on the phone he said he was not sure how long the group buy was going to last. I also asked if they had plenty of manis and he said they did. The manifold comes with the gaskets but no hardware unless you fork out another 46 bucks. I emailed him and he called me the next day so I would expect a call back from him soon.

You answered my questions perfectly, thanks man.

Well I tried logging some with my old mani and the new fp. My problem is when I do a 2nd gear pull my car just spins so I think that messes with my readings. I dont like to do 3rd gear pulls on the street. its so inconsistent its hard to say but it feels like it has more midrange torque than before. It spin the tires earlier than it did before. I logged quit a few runs with the evo gt manifold and saw highest of 35.6lb/min and with the fp mani only could get two in but it is spinning alot worse than normal and got the highest of 35.4lb/min. It is only 11* outside today so that cant help with traction. I was actually suprised I thought I would be flowing more air than this. It is only on 20psi though. My internal wastegate is blowing open and wont let me run more boost. Need to go external badly.

As soon as I ready my car, I'm gonna do some dyno runs with stock and FP's manifold for everyone. Accepting donations.

 

[chavez408]

I know its a 10 days old.
But has anyone else find any luck with dyno runs with the fp mani.

 

[kittay]

Interesting results on the link. Too bad it was an unported 1g vs the FP.

It'll def be interesting to see how the ported 2g compares on the 16g. I've been considering it for my dd

 

[Black_Bullet]

Yea i havent had luck with finding proven hard core results on the mani comparisons either.
Ive only found reviews and speculation like what im about to give...

Ive had my Fp manifold installed for at least a month now. Got it in the last group buy.

I dont have any hardcore data, but the few things i can say im positive about that changed on the car
between going from a ported evo3 exh mani to the FP are-

* The sound changed in the lower rpms when cruising. Gave it a rumbling staccato like growl.
Especially audiable for me since that i have a electric cutout and im open DP when its opened.
Reminded me of how my friends Sti sounds, but not to the extreme.


* The overall spool up to set psi felt about the same when just laying into the throttle; but it hit harder than it had did before... Maybe i wouldnt have noticed another 200rpms of spool thru a 16g...

My transient boost response when cruising around was definitly faster... My car will spool up to about 23-24 psi in 4th and 5th gear almost instantly, with like only 30 % throttle applied. Its almost hard to not be boosting on my little E316g now when cruising in 5th above 75mphs. Ive gotten some knock lately because i will be doing a long highway cruise at about 80-85mph ( extended closed loop AFRs) and wouldnt notice i would be riding down the highway at 5-10 psi the whole time. That built up heat of the constant boost + the closed loop afr's caused knock and set my knock buzzer off ( 10 count buzzer ) on a couple occasions. I have to watch it now on the highway. Though, the gas milage did seem to improve some .

* Also, this may not help and i wish i had did some logs when i first put the FP, but i didnt start retuning/relogging the car until i installed my bc272s which i installed a week or so after the Fp and when i went to tune i had to retard a good 2 degs of timing in the lower rpms under 5k...

Could that be more related to the FP or the Cams?
The straight 272s robbed low end torque/power so meaning less air flow in that area, why would i have to retard timing down low in a spot with supposably less air? Perhaps the faster spool up, more boost= more heat?(rambling)
Top end timing was unaffected for same given boost level...

Perhaps a heat soaking engine bay... I dont have the jmfab shield yet, missed out on that GB.
I will get one real soon, and im sure it will help some how.

Side note : A guy i know on the Tamparacing forums with a fp3052 said that his turbo spools a lot faster. He noted that he was able to build more boost in first gear than he had ever been able to build before. I rode in his car and it certainly spooled on the quick side for its size... That should be at least some good news right there.

 

[talonDSMerr]

hmmm still nothing? Almost been a year now from the last post. I just bought my own FP mani, but won't be putting it in til summer. Have low compression in 2 cylinders, hopefully from just a leaky headgasket..
But hopefully I will be able to fix that up, do a log with a ported 2g mani on a 14b, and then another with the FP mani. I hope I don't forget to post results either

 

[FonZ454]

I know I've said this before, I don't have any logs to make it completely legit but

- cool street night at the track - ported 2g mani - car trapped 115-116mph all night

- warm day at the track - FP Race mani - car trapped 117-118.5 all day.

Tune was very similar, might of been cleaned up... I swapped a rebuilt throttlebody onto the car (old t/b didn't leak much at all) and nothing else. I'd say the manifold did most of the increase in power... and there was also like 30-40* diference in temperature. The thing works.

 

[MaNGiNa24]

The only way to get concrete results is to jump on the dyno with the stock setup then switch the manifold & jump on the dyno again shortly after.

Logs & 1/4 mile runs help but there are too many variables & in the end the dyno will be much more consistent .

 

[pboglio]

Datalogging is consistent. Same stretch of road, same boost, nearly same logged/estimated horsepower every time.

Here's a tip with the FP manifold, test it with the stock heatshield in place, just use some wire to keep it in place. The manifold unshielded is easily capable of increasing intake temps +50*F above ambient, negating any power increases from better exhaust flow.

I've been thru the entire learning process with that and properly shielded the manifold is quite impressive in terms of power output.

That's actually a great point.

Well, MPH is fairly consistant, since it is an accurate way to measure HP. Very many don't trust the dyno over the MPH result with an accurate weight. As long as the driver didn't suddenly lift in the end, or the weight changed between setups, or he raced at a different altitude. If nothing else is done, I would look at this as concrete evidence in favor of the fp manifold.

Trapping 115.5mph with his weight (2810lbs) is 338hp. Trapping 117.75 is 358hp. That's a 20hp increase as a conservative number considering the faster time was in warmer weather. Not bad for a 16g car. That's a good increase with a mild setup.

FonZ454, did you have a heat shield? How is your intake setup? Would higher underhood temps have an affect on your IAT? The gains you've shown is what I'd expect to see out of a SMIM upgrade 20-30hp increase. This shows that there is some good increases that can be had with either manifold being upgraded even in a milder setup. Just because "the 2g manifold runs 9s" is a foolhardy notion to use it when you're trying to get the most out of your current turbo. A tubular manifold built similarly will flow/perform similarly. But the FP cast manifold is not that expensive and is worth the difference for longevity.

 

[FonZ454]

I agree trap speed is a pretty big factor and pretty consistent. All runs were driven really well. A car that consistent traps 2mph higher than it's last visit is making more power. Especially on a hot summer days, vs. a cool night where it was running slower.


No heatshield on the manifold, and the airfilter sits where the SMIC would sit... So intake temps are not underhood hot.

These runs were a few weeks apart, but they were all pump gas and tuned as well as I could get it. Boost was similar (and no matter what, would be at ~20psi at 6000++ rpms... so theres not diference in boost in the backhalf of the track really)... and otherwise the only major was the manifold. It's not concrete, but the car made more power for sure with what little changes I made.

I'm not saying the car's going to make 20more hp... but I had very good results with it, and for a maxed out setup like mine, changing "good" parts with better parts is needed to make every extra bit of power.

 

[Vanish70]

Can someone do me a favor and weigh their 2g manifold and post the results here. FP claims that their manifold is quite a weight savings over a Evo III, quoting 17 lbs. That number seems high and I was curious as to what the 2g manifold weighs by comparison. Thanks.

 

[pboglio]

They are identical in weight, I think 12 lbs if I recall correctly when I weighed them both.
It would be an interesting bending of the law of physics if it was lighter, unfortunately its not an ounce lighter. Cheers.

 

[UofACATS]

When I install my FPmani, I will datalog extensively before and after. I figure an average of a couple runs to get some consistency in the numbers will be sufficient. Like everyone else, it's going to be a while. I'm doing the clutch as well as a few other projects right now.

It absolutely will get done though, and when it does, their will be dsmlink logs. That's really the only way.

 

[habitatguy187]

Bump. Would like to hear more reviews/more concrete data.
