Reliable boost with T-trim
Saw this in a fairly old post while doing some research:
Maximum airflow: 1,200 CFM
Maximum boost: 26 PSI
Maximum speed: 55,000 RPM
Would a built 3.5 (eagle rods, 9:1 comp, cams) with a t-trim blower be a reliable and durable boost alternative to a big TT setup? It seems a built engine kept in the 400-500whp range with a gradual top end biased Vortech powerband would be a lot more durable than guys with 700whp built TT 350z's where torque kicks in early and hard.
Is it even possible to make 475-500whp blower only? Say a t-trim on a 3.5 with cams revving up to 7500. Theorically how much power would it be able make on a 3.5 between 15 and 20 psi?
I know someone on the furum has a stock 3.5 making 426whp/387wtq at 13 psi or so but I think he has an s-trim.
EDIT: Just saw the thread lower on the page. Don't kill me

Im talking to a guy who has a shop around here with a VQ S13 and if I have the money this winter I might buy a second VQ35 and build it with eagle rods. So far it seems the SC equipment + built engine is a 6000-7000$ project. I already have the Walbro, e-manage ultimate and wideband. Just need to decide if I want to keep it NA.
you could make the power you want easily. there are guys with 450-500whp blower alone on S-trims without cams, not sure on their redlines. sentry65 is one of them that I see post all the time.
why are you comparing a 500whp SC car to a 700whp TT car though? apples to oranges. at 500whp, a built VQ could probably last until the sun burns out. a TT car with the same power level will still be a bit faster though because of having a much broader power band.

I was comparing to a TT as far as drivetrain shock goes. How hard it is on the tranny and diff.
About the noise: Is it possible to keep a t-trim quiet depending on whether I use a V1 or V2? If I do this I will keep the car stock looking with 300zx TT wheels (to use the 13-inch brakes) and I'd really love to have this huge sleeper that doesnt give away the SC sound.

From what I have heard the T-trim V1 is VERY loud. The V2s are a bit quieter, but there is no T-trim V2. I think there is a V2 "E-trim", but I have not heard of anyone using it. It is listed with very similar specs to the V1 T-trim
I would say that the drive train shock of the Vortech is far less than a TT. Normally it is nitrous > turbo > SC for drive train shock. A lot of it would be on the clutch and driver as well though.

? both the T-trim and S-trim are centrifugal, no one's talking about positive displacement blowers here...
jclaw - what you're talking about is a non issue - you're not going to break anything because of the quicker spooling of a TT. the shock of a single hard shift or half a second of wheelhop is worlds more shock loading than anything your powerband is going to induce.... you needn't be worried about your powerband hurting anything in the slightest.

I guess you're right. The draw here is that a centrifugal is basically like an extension of having a powerful NA VQ (direct link throttle response, pretty good midrange, then INSANE top end all the way to 7500, hence the reason for the built engine).
Id love a built NA engine but at this point I cant justify the amount it would cost vs an FI setup that does 400+whp easily. Hence the closest thing to a NA setup - a high-revving centrifugal blower. I even get to keep NA headers.
Thats all theoritical right now since Ive never had a 400+whp car that weighs less than 2300 lbs. If this thing gets into the 11's NA I might decide that 10's are too fast for me lol.
Then theres the easy way out... stock motor + 100 shot

I'm building a VQ30 DEK + V2 and I hope to hit 400+ to the wheel, but this is theorical until everything is put together and tuned, so let wait and see what happend. But the cost of my project will be close to 15G. Like the old saying goes " You got to pay for play "
Oops I should have said 15K not G euh... but yes it is going to be I/C, with the JDUB bumper there is a lot of room for that. I'll shoot some pics later this year when the project is to a stage where you see some result.

Unless you are counting your implied body work and other things, $15,000 for a SCed VQ30 is a lot. Are you actually building the internals of the engine?
Jclaw, I think a Vortech SC is a great way to go for a VQ 240SX. It is my plan as well.
The T-trim is very very loud, I know from experience.

Whoa, no denying a blower is on that car thats for sure.
A little more blah blah...
Basically I'm rebuilding the car, wich mean freshly rebuild VQ30DEK with new Arias piston, maybe new rods but I think the stocker will be fine for my goals. I'll have the heads port & polish with better spring, valve & retainer. The lower & upper IM will might be port & polish by Aaron, but I need to send him pics over the week-end to see if he can do it. I already have Matty V1 kit, I just need to buy a V2 with IC. I'll probably go with the e-manage ultimate and what else for tuning. The car is going to be entirely re-paint with the JDUB body kit, new 18" wheel. I'm still a year or so from the end result but I'm in no hurry as my Murano is serving me well now, so I'm taking my time since this is going to be like a show car but just for my own fun, well maybe I'll do a show or two but that is just an excuse to drink beer with the boys and girls.
