Titan supercharger
 

I spoke to a guy last night who owned a Titan truck and added a supercharger. He told me the same day he installed the supercharger the transmission started to act up and completly went out the next day. He said he took it to a transmission shop and they rebuilt it only to have it go out almost imediatly. He explained to me he rebuilt his transmission twice before removing the supercharger then rebuilt the (automatic) transmission one last time before selling the truck. I explained to him i wanted to supercharge my 370z and he all but begged me not to. I have the standard transmission on my 370 with the sync rev. Does anyone think supercharging the 370 will cause drivetrain problems?:confused:

Adding more power always has the potential to cause these problems.

Did this discussion take place at a bar?

there have been numerous TT installs on AT G37's... all of which didnt have any problems...

it's highly suggested to invest in an transmission oil cooler for AT's
just like a clutch/fly wheel is suggested for a MT setup.

There are plenty of Gs and some Zs that are running TT setups that would be producing equal or higher RWHP numbers and few reported problems with the trannys. The MT will be more robust than the AT and will be able to handle more power. Your reliability will go down when you choose to boost but it will also vary with amount of power you choose to go with. If you are doing 600-800 RWHP then yeah you will most likely want to beef up the tranny as well as the rear end but if you are gonna SC and will be content with the 400-450 RWHP range then I really wouldn't worry.

Remember anytime u add power u exceed the limits of the oem parts. A side note to remember is torque ratings because that is how transmissions are measured... By torque not hp as most refer to. There are several g37 both manual and auto running 400 ftlbs or closeto it with our trannys. Manuals will need a tougher clutch and the autos may need to be upgraded as well when u reach around 400ftlbs. I hate autos due to the innefficiency of torque converters delivering smooth power to the ground and that was most likely the culprit that caused the trucks tranny failures... Just my 2 cents

Dont all conversations take place at bars? At least all that are 100% true? Ya Bullit that sounds pretty acurate because i do remeber the guys bragging on how the truck could "catch a second" as in the tires spun while the auto tranny shifted itself. After he mentioned that i kinda thought to myself that had to be some pretty hardcore wear and tear for an automatic to spinout like that. The guy did seem to know pretty much what he was talking about but then again he could just be "that guy" aka expert on everything. I am not sure what his titan was rated for as in, towing package and whatnot for beefier drivetrain bc he didnt mention anything but the truck's 1/4 time which was 13.37. I know the 370 was lightened and i assume Nissan may eventually release the car with a stock TT or SC. I just hope the drivetrain on the 370z can handle more of a HP gain % then this guys Titan could. All in all i want a car that is fast and reliable not a 10 second 1/4 mile car that always has to be tinkered with.

nissan will not release a stock TT or SC as oem.... really doubt it

GTR..... There is the TT... The Z will not have TT from the factory...

A blown V8 will have more torque than a blown V6 would at comparable manifold pressure. It all comes down to how often you beat on it. For the AT, trans cooler and shift kit are a must. The next step up is clutch packs.

This is just me, and I know I'm on the wrong part of the forum to say it, but I think the S/C is just going to cause issues in the long term. On the track, it means you need a full BBK, the transmission may have issues, the differential will definitely need a swap or a serious cooler, and engine cooling may be an issue again. That means the S/C really costs $10K+ if you want to use it (traffic light drags are obviously another issue)

I'm going to spend some of that money on track time. As they said at my last track day, if you invest the money in the car, the car goes faster, but when you sell it, you're the same speed. If you invest the money in driving, you will always be faster. I will make an exception for Travis, who already seems to be a pretty hot shoe, and who needs to get out there and spank some 'vettes with his Z...

Anyway, just my $0.02. I think this car with the intake and exhaust is already reasonably fast in the right hands. If I do drop more coin, it will be on a Caterham :)

All these issues which you mention need to be addressed before even a stock Z rolls onto a track.

This will decimate all after you put about $15,000 in it. Or more, if we have to overnight parts from Japan.

We'll put it on my tab at Harry's.
