From looking at the dyno graphs, it seems to me that the PFS IS300 was designed more for the quarter mile. That turbo seems to spool up fast producing serious HP in the early RPM ranges. At 4000 RPM, according to the dyno, the PFS car has almost 400 HP compared to 225 from SRT. At 5000 RPM, the PFS car is max'd at almost 600hp while SRT is still climbing at 400hp. Awesome #'s from both tuners I must say...

 

yes a friend of mine was there this weekend and he said that the PFS car was killing the SRT one from the start, but dropped down later which is why it drops drastically on the dyno sheet. is that correct? one thing he said that was weird though, is SRT would not actually show the engine of their car and would not let anyone see the gauges. why? I've actually seen aldo's car (the PFS one) and man it is sick. he showed with myself and the SELOC crew at NOPI, we'd have him crank his car up and rev it a few times for passers by. you wanna talk about mean sounding phew! hear it in person!

ok hope this sounds better/clearer as to what i am trying to get across.

 

sure would like to hear it!! is this for quicktime only???

 

You should hear it in person. It is absolutely wicked. I don't know how the guys could stand there and film it...the noise is almost unbearable that close to the car

 

I was there when they were tuning the SRT car a few days prior to the meet...those numbers are for real. SRT has a few secrets up its sleeve which they obviously wouldn't share especially when their competitors are present.

 

amy011079 - I don't know WHAT you are talking about because your information is totally incorrect! From the movie links , you can't fake having 128 MORE rwhp, and spanking the PFS car. Guess the movie was modified? Sounds like your friend is hating on SRT. SRT did not want ANYONE to see the inside of the engine bay PRIOR to the dyno. Didn't want a wire,or hose to somehow come "unloose" by people poking in the engine bay. With the "smells like a rat" statement, they were right to do that, plus getting crushed by 128rwhp smells like a buttkicking to me. Look on IS300.net, and you will see pics of the SRT engine bay.

LXOGOOD - Remember, maxing out at 5K, when the cars shift point is around 7.2k is NOT a good thing!

As far as the dyno graph, if you look at it you will see that the PFS peaks around 5000rpms, and then drops off with a jagged edge. What that tells you about the PFS is that the boost is NOT linear, and actually loses power in the upper rpm range. You want LINEAR power, not a spike like the PFS car, especially near the middle of your rpm range. By the time hit the 7000rpm mark, the PFS car is at 400RWTQ and 530RWHP, while the SRT car is 728RWHP and 540RWTQ. Who has the advantage? In the 1/4, who knows, probably depends on the driver. I actually think the PFS car would get WALKED by the SRT car given the same driver, and skill level driving both cars. One the street, where it counts: SRT hands down. The PFS car would lose by a couple of car lengths on the highway.

If I am wrong, someone correct me.

 

look dude don't be fussing at me i am just relaying something that was said by a friend of mine that was there that is all. oh and by the way, i haven't watched the video clip it won't load on my computer. how about you re-read what i posted to begin with because apparently you didn't read it the way it was written or something because there is no reason for you to attack me the way you just did. APATEL responded the mature way and corrected what i had heard. neither myself or my friend are attacking SRT in anyway, i just merely stated what i had been told in hopes that someone would set things straight. if it came out derogatory then i am sorry and i didn't mean for it to sound that way. but i also don't think necessarily that anyone needs to "BASH" the PFS car either. 590 some-odd HP is still alot more than most of us on here have. both cars are spectacular.

 

Not trying to start anything, it just seemed that you were putting a negative spin on a good event that was setup by SRT. Maybe I do need to re-read your post (same conclusion), and maybe you need to re-read your post also, maybe even upgrade your movie viewer to watch the both Aldo's(PFS)/ParcelPimp's(SRT) dyno runs before repeating rumors (since you wasn't there, correct?).

I mean you posting statements like "smells like a rat", "things not adding up", and your basis is "I heard this, and wasn't there", is NOT cool at all.

I wasn't bashing the PFS car either (which is a beast in person also) it just wasn't ready for what ParcelPimp had, but that post seemed like you were crappy on the SRT car/event (and the dude that owns it is a cool dude also), and that wasn't "mature" as you put it, either.

It was a good competition, which helps everyone. Thats why I started this thread...

Just my .02

 

ok well, you obviously are going to be close minded about the point i am trying to get across to you so i am just going to attempt to explain it one more time and then that's it. First of all, I never stated anything, i repeated what i had heard. no i wasn't there and no i shouldn't have made any statements since i wasn't unless they were clearer. (because obviously you got misconstrude) but geez you are also trying to out words in MY mouth. i never said anything about anyones character either. i am sure parcelpimp is a cool guy, never said he wasn't. no, i wasn't trying to put a negative spin on a cool event either, wish i could've been there(like i said in the last post i wasn't downing SRT in anyway). i never started any rumor either. i just said that SRT did not show the engine bay at the show(which is what i was told) to which YOU corrected me remember and said and i quote "SRT did not want ANYONE to see the inside of the engine bay PRIOR to the dyno. Didn't want a wire,or hose to somehow come "unloose" by people poking in the engine bay." so that means i didn't lie, i just didn't know that they had shown it later, nor their motives for not showing it earlier. that is why i posted what i did, (like i said before) i wanted SOMEONE to tell me what the truth was because obviously i didn't know since i wasn't there. AND ONCE AGAIN I WILL SAY THIS i did not mean for my comments in the first post to sound derogatory and if it did, then i apologize. next time i will make sure to put a disclamer on my posts so everyone knows what i am trying to say. i will go back and edit my post so no one gets the wrong impression on ANYONE OR ANYTHING that was at the SRT bbq if that is what you want. and i will repeat myself because for some reason you just aren't hearing me I DO NO HAVE A PROBLEM WITH SRT NOR ANYONE THAT WAS AT THE BBQ, I MERELY WAS TRYING TO INQUIRE ON SOME INFORMATION THAT WAS RELAYED TO ME FROM SOMEONE THAT WAS AT THE EVENT. SORRY IF I OFFENDED ANYONE THAT WAS NOT THE INTENTION.

 

okok, everyone calms down. take a deep breath, no harm done here. i understand the discussion, but don't put in too much heat

 

sorry henry!

 

Cool

 

guys, no biggie. i definitely don't want to make myself sound **** here. i have no problems with you guys discussion, in fact i found a lot of useful information. just that i felt the heat was building up so i posted what i posted. i wasn't pointing at anyone at all so don't worry

 

I think if you look at any other PFS dyno, you will see that the fall off after the peak hp is not common. There was obviously an issue there whether it was a traction issue or not on the dyno is unsure. I am not sure if there are any better PFS sheets online, so let me use mine as an example of a much quicker boosting turbo. MY car pops above 500 rwhp at 4400 rpm and stays there until redline. That means I have 500+ rwhp for almost 3000 rpm. My torque jumps over 300 rwtq at 3500 rpm, 450 at 4000 rpm, and about 550 rwtq at 4400 rpm. This is the huge advantage of the more modest sized turbos. PFS is a similar sized turbo, so I think we can assume that their dyno at the SRT even is not a fair estimate of their car.

In the Supra world, there are cars they call dyno queens. These cars produce massive horsepower on the dyno's, yet lose consistently to cars with lower hp, but a much more usable curve. The car with more area under the hp curve will almost always win the race. Therefore, just because you have the higher hp peak doesn't mean you have the faster car. Just some food for thought.

 

Thats true because you have to factor in "usable" horsepower. But don't you think the SRT (and your car from your dyno (DAMN! Waxman, thats a smooth powerband! ) would have an advantage since both seem to hold that power instead of peaking at 5k then dropping almost 100rwhp like the PFS car? Not trying to start anything, just asking (since you of all people have had the most constant boosted IS from the jump from what I have seen/read on the 'net).

I'll agree that the dyno results can give a false impression.
