yes yes yes it just wont last why waste time and money when youre gonna have to get the single anyways
thats silly...no one HAS to go single. not everyone wants a laggy highway car..simple or not.

My twins have two years of hard driving on them at 16psi and I have no leaks..no cracks..no heat issues...and no problems. my m2 set is still cherry.

congratulations you are the owner of the worlds first twin-turbo set that outperforms the single turbo

not the case.... beelzibub.

my car does not outperform a single turbo car in the sense you insinuate. I would never say that.

compare my cars sheets to the majority of the singles on the catenet site and you will see that in terms of streetability and response my setup is superior. however...id get eaten alive on the highway.

as I said..it is all about how you want to drive your car. I hate lag. singles have big lag. that lag would kill my enjoyment factor as I would not be able to enjoy it AT ALL without speeding. I like to zip around town and do stoplight to stoplight fun. I couldnt do that with a single. That is why I spent my cash on the m2 set.

you can take the lag and stick it in your tailpipe.

if you dont mind lag...go single...its simpler...easier...and will smoke just about anything on the highway.

if you live in the city...beware.

send a pm to wargasm to have him pass you the link to his dyno sheet site. compare the charts. look at the power down low on the stockers vs the 99s vs the m2's vs the rx6 vs the gt3540. compare the powerband. if you like to drive a certain way, pick a turbo setup that will accomodate your style.

the rx6 is booty expensive. the gt35 kit smokes it on the top end. why go rx6 when you can get nearly the same peak power with the m2 set or the 99s and good tuning....and have even better low end response.

you might push 430 on an rx6 with lots o tuning...most with them are pushing around 360-400 from the dyno sheets i have seen.

Well I have a dyno sheet that shows my 3540 putting down 10 less HP at 3k RPMS as healthy stock twins car and a TON more after 3k RPMS. Also I get the boost I want every time I push down the throttle. I will e-mail you my sheet if you like. I made 404.2 RWHP at 15.5 psi on a stock Reman Mazda motor. PM me your e-mail address and I will show you the Dyno sheet. THE 3540 now on my ported motor (havnt dynoed it yet) pulls even harder than my stock motor did. Also the power doesnt drop off and it spools at break neck speed.

Please post the sheet. I have yet to see a dyno sheet for ANY single at 15-20 psi that makes the same torque as my near stock car made at 10 psi (downpipe and cat-back only) below 3500 rpm. Let alone, my mildly modded car now at 12 psi. Please prove me wrong. It might make me more willing to go single...

zoom...what was the cause of your lost motor? how long has it been since your car was on the road? do you finally have your car back?

nice sheets. are they sae corrected?

cant wait to see the new dyno sheets.

I still wouldnt trade my immediate response for the gains of a single.

One motor was lost due to Crank angle sensor wired Backwards by KDR. Another Motor Destroyed by Secondary Injector not connected to harness, KDR. ANother Motor blew on the Dyno "Unknown cause" KDR. Working out Bugs. I have a New mechanic now. Ito at JR's Rotary. He is a good guy and getting the car 100% for me. They are SAE corrected.
I would race you with your twins and I bet 100 bucks you couldnt even take me off the line with your Responsive twins LOL. I raced my Buddys STI Subaru, He has Mods and has dynoed his car at 325 to the wheels. He runs and Intake, Full exhaust, Greddy E01 EBC with 2 or 3 psi more boost than stock. A few other mods and AWD!! I still beat him off the line with my street tires and I was spinning in 1st and second. Missed third gear went into fifth. Downshifted to third again and still won by about 3 car lengths. (short race) to about 100 MPH. I have alot of faith in this turbo. I have driven my own car with stock twins and full List of Mods. All M2 stuff and Power FC. It just didnt pull heard until the second turbo kicked in at 4500 rpms. I would utterly destroy my old set-up in every way. I also had a problem with getting a laggy Turbo. If you drove my car you would LOVE IT!

allright cracker-boy ...have you ever ,EVER driven a PROPERLY tuned single turbo rx7
not likely ,and i am not talking huge t88h`s and the such ,a decently sized single will do like a 60-1 for instance ,but then again you probably wouldn`t know
take it from a man who`s had both ,single doesn`t necesarely mean big lag

Well I had Video of the race as well if you want it IM me at Mik3ymomo You can clearly see I in no way way get beat either off the line or midrange or top end by this modified Subaru STI. Its pretty even off the line but hey. I dont have AWD either.

Wow, that is pretty good low end for how much power you are making. You seem to be getting boost a few hundred rpm faster than other GT35/40s I've seen.

Someday when my car becomes just a track car/weekend car, it looks like a ball-bearing smaller single might be in the cards. For now, I'll stick with my good torque at 2500 rpm twins.....

felix...post your dyno sheets. dont be scared. its ok. I will throw down a six pack bet that your single doesnt have the guts down low like mr zooms here. his is the ONLY one I have seen to date with that kind of response. I love being proven wrong. learn something every day huh? zooms old dyno sheets are nice. Lets see your sheets mr finely tuned machine you.

zoom..i agree with rynberg...yer car seems to be tuned well for the power you are running. compared to EVERY single setup on the catenet site yours is the exception. (unless some new charts are up that Im not aware of) well done. you must have quite a beast on your hands. who tuned it?

i would have raced ya when i was in mass but you couldnt get her running in time. I would not have expected to win...though I would have loved to see how she did.

in terms of response im not talking about drag racing drop the clutch smoke the tires bizness. I dont drive my car like that...at least on a daily basis..hehe... I drive from stoplight to stop light and tear around town.

yes..im sure i would love yer car...were you able to get it finished before the snow fell? I couldnt handle the weather up there. pure nasty...and the roads were unbearable. austin is great man. there are some wonderful roads around here and the ladies are even better.

I think mine has pretty good low rpm response.

I wish the ignition pickup was working when I made this run but that slight flat spot from 72 to 82 kph was my lag / response. Otherwise it pulls hard the rest of the way. This is an APEXi RX6A.

That time the tune was done by Dave at KDR. I would love to move to Texas! Find me a decent job and I will come down and live there! I have a large ported motor now and the same turbo. I want to dyno it before it gets put up for the winter. I expect too see 430-440 at the wheels on pump gas and 15-16 psi. I may have lost some low end but i am not sure yet until i dyno the new motor. Ive been driving it but missed the last track day by 1 day!! Tracks closed Oct 31 up here. I race randomly around town. C5 vettes and STI's and whatever the local guys can throw at me. I own them all. Even the C5 couldnt take me off the line. Maybe I am just a freak but my car has always had good low end. I highly suggest a single upgrade. Knowing which single is always the challenge as not all Singles are equal.

There were two differn't models....from what i have read the TCW76(RX6A) was the model with smaller exhuast housing, and the TCW77(RX6B) was the version with the larger housing, it was also mounted in a differn't way. You may want to ask Maxcooper or Dougie Fresh 007 about these turbos.
