Peter Farrell eh.?
 

How good is the quailty of Peter Farrell parts compared to big brand names like hks, greddy, apexi, etc.. I am asking because I got my eyes on a Peter Farrell intercooler, cold air intake, and exhaust.

Depending on your needs, the IC is very nice (as it allows you to retain your airpump and stock battery location). If those two things aren't important to you, then the IC won't be a big deal (aside from being much better than stock).

The intake and catback are ok. Nothing really special about them, but nothing bad about them either. ;)

I don't have the PFS catback, but it is very light and is supposedly made very well. It's a bit louder than the RB with a deep tone.

I do have the PFS intercooler and intake. I think they work very well and they have decent fitment. One issue is the cold side intercooler pipe rubs against the stock battery tie-down. I solved this by using a 51R battery in TurboJeff's SS battery tray. Another issue is that you have to remove the IC and intake together, which can be annoying, but not that big of a deal.

If you can pick up the IC and intake used for about $900, you are doing pretty good. The IC performs nearly as well as the M2/ASP medium. The intake draws only cold air from the nose, so it is the coldest air intake available. It's also a real plus not to have to remove your air pump or buy a Greddy elbow.

I would recommend them.

Thank you for the info.

the ecu is a clunker...its like comparing a first generation nintendo to an xbox...compared to the pfc or haltech...

the rest of the stuff is fine.

IC is real nice.

The PFS IC is fine for normal street driving and some racing around and its used price is normally very desirable but actual flow rates and efficiency compared to either ASP IC is not really even in the same ballpark. It's on the order of the difference between the stock IC and the PFS. The standard "you get what you pay for" does apply. As I said though it's not a bad unit. Just a different category. Ack crying baby sorry gotta go : ).

I have the exhaust and like it alot. Some people have told me to get an apexi or hks unit, but i like the pfs more than enough to keep it (came on the car). Very light and well built.

Why do I never see people bringing up the discussion of PWR cores?

why do you wonder that clayne?


im going to be the first to say...if you want a great IC...the ASP is tops for stock mounts. Wyum is the IC man. I have an m2 unit of his design..the same design...and it is indeed a superior IC. it also has the least pressure drop of any of IC's to my knowledge. he isnt trying to sell u one. its a fact.

mr wyum... do you know the number differences in regards to flow?

I believe there are reviews and measurements on www.scuderiaciriani.com for these IC's but i am not sure if the pfs is included amongst them.

I'm adapting an older, slitely used, PFS IC but it's bigger than the current setup and it came without the plumbing. I'm having to build custom mounting brackets and re-route hoses and all and I'll have to build a custom duct. I'm taking pics though and I'll post them as soon as I'm finished - about a week -

havent they only been around for a year or so?

There are 2 types of PFS intercoolers.

The first one is puny, it has red endtanks and you can keep the battery.

Then there is a giant SMIC the same size as the ASP one that has a duct as well which requires a battery relocation.

I have the giant one in my car, I will try to take pictures and post it.

Oh yeah and for the record, I like my giant one....keeps the air intake temperatures very very cool and is pretty high quality

I can't speak for his IC or his Intake kit, but I can say that his 3" SS Cat-back w/ 4" tip is a NICE exhaust. It's REALLY high flowing (straight-through), but not nearly as loud as some of the coffee can exhausts that Blitz, Apex'i, etc. has.

I think the real reason Peter's IC has a little higher pressure drop than M2/ASP mediums (or other similar) is the fact that it has a tubing welded on to come from the y-pipe crossover, and to the standard elbo. This requires some tight-radius bends... but is nice for retaining those two items. I recon if you were to stick those tubes on other IC's they'd have a higher pressure drop too... we're talking standard spearco cores on most units out there, and theres really no magic to them. Its also not as tall as the M2/ASP, and that may contribute as well.

The catback is real nice... they say theres nothing special about them, but how much "special" are you expecting from a muffler for god's sake? Its VERY light, made well, flows well.

Actually the numbers I'm talking about don't include tubing. It's just based on the cores only. The difference in core height is the major reason for the difference in performance. I'm of course only talking about the standard IC he sold with the cast endtanks. Overall it's just a much smaller core. But when you have used ones selling for $400 it's hard to argue with that kind of price unless you're pretty serious about performance.

I have the PFS cb and i like it a lot. I feel that it has the best exhaust note out of all of them and it is not a huge riced out can like some other ones.

I really don't like the way how the PF IC is.

But that's my opinion.

Do you have any numbers to back up your statements ?
I mean - did you do any measurements of the intake temps or are you just talking from the top of your head ?

Just asking, because you are biased ofcourse ;)

Care to give any actual reasons?

Oh and I dont think you can get the PFS IC for much lower then $600. I got it with the intake for $700 (a hell of a deal if you ask me) ;)

Funny you ask because I just happen to now : ) Someone posted a link to it in another thread.

PFS IC

Core 3.5" x 10.4" x 10.5" CID of core 382.2

CFM of air flowed at 1.5 psi of pressure drop 410

Pressure drop at 10 psi and 6000 RPM 1.25 psi

Efficiency of heat transfer at 5mph air speed through core. 43%

Efficiency of heat transfer at 20mph air speed through core. 71%




ASP Medium IC

CFM of air flowed at 1.5 psi of pressure drop 620

Pressure drop at 10 psi and 6000 RPM .6 psi

Efficiency of heat transfer at 5mph air speed through core. 56%

Efficiency of heat transfer at 20mph air speed through core. 86%




ASP Race IC

Small core unknown what application it is used in. Example of small core

Core 3.5" x 6.6" x 11.55" CID of core 266.8

CFM of air flowed at 1.5 psi of pressure drop 320

Pressure drop at 10 psi and 6000 RPM 2.2 psi

(This is actually a dense fin design core and pretty good for its size)

REALLY nice, Kevin. Good work.

Thanks, I appreciate it.
Numbers are always good :)
