I am to blame for some of the delays with lack of instructions. I had to push Sam for time as my build had a definate end date that need to be reached.

So how is the car doing now after a few miles on it with the kit? Got good power when you stomp on it? Gas milage?

True guys! My build is also holding up a good bit of work as I have an approaching magazine cover Sam is putting a lot of focus to finish my build. Things will speed up so stay patient.

You selfish bastard, you! :rofl2::rofl2:

well as for it holding up over 5000 miles on it now and no issues still feels the same at foot to the mat as it did when i first got it. as for gas the wife has not seen mush of a differance with her milage. it seems to be around the same about 9L/100km

Delays suck, but at the same time, for the guy at home trying to do an install, i bet he/she will really appreciate someone spending the extra time needed to make sure the instructions and kit are 100% correct. Probably more important is that the easiest possible installation method is achieved. We really don't know the process used to finalize the instructions and kits. i'm guessing it will be closer to a factory service manual level, than the some of the black and white 6 picture crap you get with most aftermarket parts.

Shumby, I'm sorry I haven't been able to keep up to date. I remember hearing something along the lines of that you couldn't hold boost with the long tube headers. I figured it was because of a leak and they've since fixed. However, did finding and fixing the leak allow you to use the long tube headers? I honestly think GTM has greater hardware than Stillen but this issue with the long tubes is dissuading me. Lastly, is it because of the AT tranny that you don't want to go above 350 tq? Anyone have an idea how much the MT can handle? I hope it's above 400lb/tq.

Soon... (For the MT)

Who builds our MTs and is it specific to the 370Z? I know Tremec, which makes a number of transmissions for multiple manufs, has max torque ratings on the spec sheet of their website. Wondering if this info would be available somewhere on our transmission as well.

Our manual is manafactured by Aichi Kikai and is rated at Max 332LbFt.
(that doesn't say it can't take more then that, this is a rating for the total transmission assembly)

The transmission program is the MRA70 (ZG6) and also goes into:

Infiniti EX
Infiniti G
Mercedes-Benz Viano
Mercedes-Benz Vito
Nissan Frontier
Nissan Navara
Nissan Pathfinder
Nissan Skyline
Nissan Xterra

Allthough not all of the above are produced by Aichi Kikai...

(the automatic is made by Jatco and is rated at 295 LBFt)

Hope that helps... :)

Thanks for the info. Rep added. :tup:

If I'm reading this right then Nissan put more torque from factory on the AT than the manufacturer stated was its "max." I think the highest tq Z on the forums is Fusz I guess I'll ask him how it's holding up.

No, the manufacturer of the transmission rates it at 295lb-ft. The stock 370 puts out 270 lb-ft.

duh oh yeah my bad, I think it can handle way more but for liability reasons they probably underrated otherwise Nissan could argue that the transmissions don't meet the stated specs.

Well manufacturer torque specs generally err on the conservative side, but they're not too far off of the true max numbers.

All I know is the MT rated at 332lb-ft is seeing up to 400-415lb-ft in some of the FI applications we have seen so far, which will make for an interesting longevity study. Probably not the best idea to power-shift a TT car on a stock transmission. :P

Though I seem to remember the TR3650 trans in my Mustang was rated at 350 lb-ft, though we had plenty of guys pushing 500lb-ft or more through them and they were (seemingly) OK.

Just a thought, but a component is only as strong as its weakest link. Maybe the clutch is the limiting factor?

This is what I was wondering... which part of the transmission is rated at 332 lb-ft... :confused:

The 4.6l SOHC GT engine makes 300 crank tq stock and dynos around 260-270 wheel tq. I had a 2001 that i ran up to a 150 shot on which takes it to at or above 400 wheel tq and I never had an issue. The stock clutches were very very good, as well.

Yeah, I know they were pretty stout. I had a 2003. Was your 2001 a T5 or TR3650? I think they made the switch (to TR3650) mid-year 2001.

I had the 3650 heavily modded with no problems. I think the Z transmission can hold upwards of 400lbs/tq, does anyone know how the z33 trannys held up and if they are the same manufacturer?

350Z's had the same manual...

Remember that 332LbFt is 450Nm...

I had the TR-3650. I had a late year built 01 (November). It seemed like the part that broke first on the TR3650s (when they did break) was the input shaft.

Yup, input shaft issues. That was really all I ever heard of. That and there was a TSB on the 2nd gear synchro.

did this car ever work?

:iagree:

We did end up going with the black coating so it took a little longer. here is few pics for now, we will have a full update in the next few days .

Also planing on bringing few cars to the up coming Fontana Nissan meet for anyone interested to see the product first hand .

Hope to see you there .

424STD? Whats that in SAE?

Lookin forward to seeing your display Sam!

Why are these S/C kits coming in under the advertised numbers?

http://www.the370z.com/forced-induct...tml#post423546

ummmm... what are you talking about? :ugh2:

Does he have any Z in house installs on this kit?

So stage 0 "up to 450" makes 42X and their stage 1 "up to 500" makes 452 and you think thats correct numbers?

Should be stage zero ~425 and stage 1 ~450

key words are "up to"... he did not say at 8 psi stage 0 will be at 450... he is trying to differentiate the capabilities of the different trims of the Rotrex compressor... perhaps actually reading and understanding the whole press release would help :tiphat: ... also check out the dyno sheets at the end of the press release... maybe those pictures will be easier to comprehend..

I did look at the press release. Thanks for being a jackass an insulting me rather than reading my post.

Stage 1 on a exhaust-modded 370z should be closer to 475 or so if the advertised result is "up to 500". You cant have an "up to 450" and then the next stage up only makes 452. Thats dumb.

I guess factory 370z's come with "up to" 1500hp. key word "up to" :rolleyes:

I would say the "up to" parts depends on different mods, PSI, altitude of where car will be , temp etc. Its not an exact science so I can live with up to. The actual numbers seem to be about par for SC cars out there that are carb legal.

I could live with "up to", don't get me wrong on that. They just seem way low for the top of the "up tos", thats all.

I figured one could get 430-440 out of the 0 kit with a decent exhaust setup and a worthwhile tune. and at least 470ish out of the stage 1. Not 425 and 452.

What a retarded argument...

If it's anything like what Stillen advertises, it is estimated BHP. Which is useful for people paper racing based upon the stock 332 BHP figure. It's actually safer to state the estimated crank horsepower output of a kit since dyno and atmospheric conditions vary so widely. 500 BHP can very well end up just over 400 WHP on a low-reading Mustang dyno.

The rating of the horsepower output of our force induction systems whether a twin turbo or the supercharger set up is in BHP (brake horsepower ) just like how Nissan rates the car on their web site, the 370z VQ3VHR engine is rated @ 333 HP . so i think your are looking at the press release and seeing up to 500 HP and then comparing it to the dyno graph we have posted, the only problem with that is you are comparing WHP ( wheel horse power) to BHP (brake horsepower ) and i think that is what's causing your confusion .

So our stage one kit is rated up to 500 hp which translate to about 415 WHP depending on the car and the dyno and the same goes for a stock 370Z with 333 HP from the factory that will also dyno @ 275 whp

Hope this help .
