Forced Induction & 7AT 370z Info

jchammond · 04-02-2015, 02:37 AM

i been considering giving mine some boost soon-thinking more down the line of the GTM twin SC kit....i do not want to open exhaust yet & wanted to try and keep quiet.
currently stock 11' touring/AT just over 275WHP & 243TQ....quickest pass in qtr. 13.13@104.89,,,not to shabby for open diff 3.359:1 ratio.

first off, stay away from GTM!

they are out of business and ripped off many people here for thousands and thousands of dollars.

secondly if you go the turbo route you can still have a semi quiet exhaust. turbos act like giant mufflers.

Hey guys, just to add onto this thread I was wondering how everyones reliability has been with the stock AT. From reading the thread im getting that gear 1, 5,6, and 7 are pretty much off limits. I'll be using this as my daily driver so im just trying to get an idea at how fragile this transmission really is with the supercharger.

supercharger really wont make enough power to worry about the tranny. from all I've seen just tanny cooler will do the trick for the SC

Don't forget about having UpRev increase the pressure in the tranny. But I think most NA AT guys do that too. I don't know all the details cuz I drive a real car with a clutch pedel

So then what was all this talk about avoidong gears 1, 5, 6, and 7 if you have a SC'd 7AT? Is it still a concern? Im not the type to run it on tracks or redline everyday but ofcourse i do enjoy taking it up a notch every now and then. Driving 22 miles down and back for work, I shouldnt need a tranny cooler would I? I know it wouldn't hurt but I like the motto of, If it ain't broke don't fix it. Lol

ANMVQ · 04-02-2015, 07:51 AM

unless you plan on building the trans( and there is no real solution yet) I'd stay away from a Turbo, the WTRQ will kill the trans. A SC is better as it will build WTRQ and throw it all at once at the trans. You wont make as much power but the tranny will hold, or at least longer, I ran my SC kit with 330 WHTQ and the trans was fine, Motor blew tho

457 WHP

..........no way of building the trans? you don't get out much do you? lol

level10 makes a built tranny that can handle over 700tq

also Tony at FI now make their own AT upgrades which paired with their TT kit set the 370Z 1/4 mile ET record.

just saying.

Hey like your tip on Level 10 transmissions - thanks- been thinking about going with a STILLEN S/C - is it really that necessary to do the tranny at the same time - Costly about 7k for complete Bullet plus the converter !!

theDreamer · 04-02-2015, 09:11 AM

I have made some updates to the details, GTM is now listed as out of business & have added Fast Intentions & Level10 with what details I have uncovered. If anyone can get me more details (potentially email) on the Level10 370z transmission built, components used, cost, etc. and send it my way that would be very helpful. Fast Intentions has not officially released theirs yet but have given some details on what they are using but no pricing currently. Will add more details on both as they come in.

What I added:

Quote:

Fast Intentions: Know details of upgrade so far - Upgrades include: Excedy Clutch Packs & our Billet Aluminum Flex Plate (SFI approved.)

Level10: Please contact them directly as their website only lists 350z transmission, but have completed multiple built 370z transmissions.

Level10 Built from Scratch - Details
Level10 Send Yours In - Details

My correspondence with Level 10 regarding the cost of their transmission upgrade

The BulletProof Transmission upgrade is rated to 750hp. Once upgraded all gears will be capable of performing under boost. The turnaround time is 3-5 business days. The Price for the bulletproof upgrade is $3995. This includes the transmission, ValveBody and Torque converter. Let me know if you have any other questions I’m always glad to help!

The price I quoted you is for the upgrade which uses the transmission currently in the car. The upgrade includes the Level 10 High energy internals, Super pump upgrade, BulletProof ValveBody and BulletProof Torque Converter upgrade. We do carry the Bulletproof Transmission in stock for 6596+$1000 Refundable core + Shipping this unit if for the coupe only we do not have one for the roadster .

Is there a difference between the 7AT on a Coupe vs a Roadster?

It may have a different pan or linkage parts if there are differences in the undercarriage due to the need to strengthen a roofless chassis.
