i actually had a motor transplant in mind, but would like to know what sort of performance gains & price to expect from the turbo kit first...

I would of been waiting on race design hehehehe

Still haven't got my car back I want to test out these babies =)

Be interested in extractors - but how much HP gain is there?

elmo · Post by **elmo** » Fri Aug 08, 2003 10:27 am

More like better throttle response down low that horsepower gain.
Heaps torquier below 3000 rpm. Can drag slower cars without using mivec now, just to tease.

That's funny, coz one FTO i ran against with extractors and FPR fitted (albeit not RPW) only overtook me once we hit about 100kph

I thought this was normal, ie. losing some oomph low end, but gaining in the high end coz it needs more time to build up pressure.

G1, what about the dyno charts you and Simon got at the dyno day?

I think Simon has got extractors (not sure if it was RPW ones) fitted if I remember correctly from one of the previous message threads?

I think that would be a good measure up (Extractors Vs Stock).

oh yeah defintely, he had higher max power.

and no his wasnt the RPW

im more interested in low-end response for everyday driving and fun from traffic lights to lights

so im getting contradicting stories here, simon's car defintely increased in horsepower as can be seen plainly from dyno chart, and his low end didnt seem to improve at all. then elmo says he didnt gain horsepower, but gets better throttle response from below 3000rpm.

so for me i guess i prefer more low end response. i would be interested to see MADFTOs results and comments.

oh and i still gotta get those cruise pics to ya somehow

Yeah, someone out there must have before and after dyno-charts for the extractors mod.

As for the pics, can you email them to me?

BTW I lost your phone number when my mobile crapped itself. Stupid "Card Errors".

Yo G1, the extractors definately make it more drivable down low, but i have no dyno figures for power etc so I dunno about up top.

Your mates are obviously a bit different, or there is another difference somewhere.
Both cars Manual?
Both drivers changed at redline?

Aha, G1 you got big exhaust on your car hey? MMM still doesn't make sense?????
Who thinks RPW should pay to put my car on Dyno and get some figures to back up their product?

yeah i have extractors and FPR....better top end i reckon...dont know about low end....

i raced another GPX without extractors...i think we both had air filter and exhaust though....as i remember it, i had a pretty bad start ...lots of wheel spin with my sh*tty tyres that i had on before...but i caught up pretty quickly once i got traction.....so its hard to tell whether low end was improved cos of my bad start...

took on a prelude with a type s conversion last night too...another win for the FTO

Yeah Elmo, I think RPW should do a test case on your car. It's only for the good of the FTO community right??

I've seen a pic of the FTO stock flex pipe and compared to an aftermarket one, it's definately more restrictive (in stock form). But from what I can gather from the RPW website, it's the length of the headers that determines lower end torque and power across the low to mid range.

dyno runs are soo cheap, and like go on a dyno day and its about 30 dollars

elmo · Post by **elmo** » Mon Aug 11, 2003 10:24 am

See i dont know too much about this back pressure stuff, all i know is that my car is nicer to drive below 3000rpm now and i personally haven't notice that much difference up top, and not through lack of trying hehe

Not just for the good of the community, it is standing by their products.
Everyone here would like to see some dyno results so they know for a fact what these things do. All the words in the world aint nothin compared to some hard facts, like a dyno sheet.

Gonna do it myself eventually anyway but thought it would be an nice gesture to the gang. Unfortunately wont be able to do before and after though but mine is stock except extractors, FPR and RPW cold air intake.

hmm, they look good. Wonder when the race system will be ready?
any idea of prices?

MattG · Post by **MattG** » Mon Aug 11, 2003 11:36 pm

Hmmm can't remember you would have to check with David at RPW for prices - but a while ago I thought they were around the $800 mark (I could be wrong).
