Topgunz - air to air upgrade

bcfromfl

Well...I guess at my age, I'd be more than happy with your A2A setup. I just don't like the torque curves with turbos, which is why I'm going s/c, and want an enjoyable, reliable, fun car. e85 isn't readily available in my area. If I do go with the 928 build after a few miles on the Si, I wouldn't boost pressures higher, and keep them at ~9psi. I'd like to see what others experience with the 928, and if it really provides noticeable and earlier torque.

I'd also probably have a difficult time convincing the wife that putting more money into the car will reap huge rewards!

Fair enough.

FWIW I had the stage 3 street with quiet disk and i loved everything about it. Next to stock feel, barely audible, not grabby and it held 510wtq all day. If i ever need a clutch again thats the one id buy. The stage 2 Im sure is very similar with a slight lighter feel and probably cheaper.

Stage 3 with quiet disk, are we talking southbend or Zspeed?

Ordered the ECB-1 with flex fuel sensor, going ethanol right off the bat. about to order the RFS, gonna skip getting the billet fuel rails and also unsure if I really NEED the billet tophat

It's a good idea to go billlet top hat, as our plastic one break often. Might as take care of this weak link while your there.

Early G37 often have a 350z fuel pump housing which doesnt have the hat breaking issue of the 370z or later G37 that use 370z style fuel pump housings.

I have not yet come up with a way to determine which fuel pump housing is in the G37 other than just pulling it from the tank and looking at it.

That’s interesting. Wonder which one I have. How early are we talking?

I am not sure. I think it goes several years in though.

I have a question:
With the 7AT, Can the OEM Transmission handle the following upgrades:
- 3.0" & 3.47" Supercharger pulleys
- 9 PSI Pulley
- A2A Kit
- 1050x ID
- 928 Impeller & High-Speed Bearings / Seals on V3 SCi

I understand that the OEM Auto Tranny can handle up to 425 ft lb. TQ max safely, anything past that is a risk.

Thats why I ask

See my other posts, our stock autos don't last long when boosted. I tried mine has lasted 20,000 with a VERY CONSERVATIVE tune just about 400whp. That's with a 19 core Setrab cooler on it and SEB increasing the line pressure also.

Ok.
So I would be pretty much driving a Tranny Time Bomb until one of three things happen:
- Upgrade it with a level10 Tranny
- It blows up and Im forced to get a new one
- I get the Z1 Excedy Clutch Packs & FI Aluminum Billet Flex Plate

This is assuming I have said upgrades I listed a few posts up with a very conservative tune.

Welp. Upgrading the 7AT is what I will go for ASAP next year lol.

TL;DR - made 440rwhp on 93 US fuel equivalent with MAF's maxed out (UpRev).

So not bad news from me guys, finally got my limp mode thing sorted out, it was infact the flywheel as suspected, so if it ever happens to anyone else, car would only rev to like 3k, ran like a complete dog, timing was stuck on 25 degrees.

Now the good news, finally got word my car is starting to be tuned, almost finished so should get it back this week (public holiday tomorrow here in Australia for ANZAC day so hopefully Thurs/Fri). Car was making around 330rwkw (about 440rwhp) on 98 RON Pump fuel, about equiv to your 93 when the MAF's maxed out, was previously UpRev tuned so had to stick with the same guys to try work out what the limp mode was. Don't have a dyno sheet yet, will try get one when I pick it up.

I'll be going ahead with the UpRev GT Maf's and switching to E85 + final tune when they arrive. Will keep everyone posted in the coming weeks, this gives everyone else the other option as I'm not sure if anyone else is still running UpRev with this kit + other mods.

Why not just run ecutek?

mikey1600

See previous posts in the thread, last thing I'm wanting to do is try switch to a different tuning software/tuner when the cars been in limp mode for so long and hadn't been tuned at all with all the new changes, SC upgrade, injectors, pump, a2a kit, return fuel system etc..

I don't think any of the boosted guys are running UpRev? I ran UpRev for my NA tune, but all fingers pointed to transitioning to Ecutek when I transitioned to forced induction. Given the level of experience of the guys tuning our cars (Seb and Eugene), you could easily find a very solid, relatively drive-able starting tune with Ecutek, with the second revision most likely being daily drive-able. The UpRev MAFs won't function with Ecutek, to my knowledge.

Good luck with everything man!
