Good to see that this thread actually brought out some of the folks that I was looking for. Keep 'em coming.....

Did some tuning today... Will start a thread in a few days when I have time. Car made 524rwhp at 7.5-8 psi. I read some concern about lag without the BBs, I'll have to look at the graphs again but I believe I was past 300rwhp before 3500rpm... Comes on strong enough to completely blow the tires off so I don't see any room to complain about that. Might push it further soon but reached the end of my current comfort level with the Uprev for now. As I learn it more I'll go a little further. I want to research my ignition timing results with e85 and make sure I'm in the right zone. I'm running a lot more advance than a regular gas tune, but when I pulled any more it was losing lots of power. I'd like to do a 10psi pull tho, which should be 600-610rwhp... Just want to tune it there then run it around 550rwhp.

Nice dyno numbers on E85! More force induction 370Z owners should take advantage of E85. By the way, what size injectors and fuel pump or pumps did you go with it? Post some video of this beasty 370Z.:driving:

We performed a great deal of work on a Nismo as Dai sated. The car laid down 598rwhp before running out of fuel. For cooling it had a Z1 34row oil cooler, CSF radiator and a vented hood.

Last week we also tuned a GTM Stage II TT Nismo that laid down 544rwhp. And as far as the driving experience the GTM kit pretty much blows the 20G out of the water. The Greddy feels really lazy kind of reminds me of driving a Z32 with larger turbos. Laggy but when they kick in they really kick in. The GTM kit pretty much is a rocket every time you shift gears.

Hope this helps you in some kind of way :).

LOL...sounds like having a Z32 with some JWT700's. Hold on it's almost there!

Sorry. I had to. Lou left that one wide open.

Now back on topic.....

.86 housing or .64 housing? Feels kind of like the .64 housings. .86 housings were garbage.

BB's - .64

roplusbee 08-11-2011 11:14 PM

That just means you need to keep your RPMs up the when running 20Gs if you plan on playing with folks. That gives you a good means to stay out of boost when you are attempting to be fuel conscious as well. Gotta hunt for the good stuff.

milo 08-12-2011 02:34 AM

To me, it would seem like LAG would be overrated in a Greddy Twin Turbo kit considering that the 370Z has a high compression engine. Granted that the GTM Turbo kit would spool faster(ball bearing vs journal bearing).

My main question would be.....the fitment issues between the two turbo kits?
Which one got hotter during aggressive driving?

phunk 08-12-2011 02:58 AM

Journal bearings aren't really the problem, that hardly effects the spool on small/mid turbos. The 20g are pretty large, and capable of over 900rwhp... That's probably where the extra lag is coming from. However, I would NOT call it laggy at all. Just driving spirited around town they spin right the hell up sometimes easier than I really wanted the power to come on. Part throttling around you can consistently feel them pushing air and increasing power before even going into positive manifold pressure. In terms of full throttle, both setups are well into full boost below racing rpms.

Pretty soon, I will be able to post up my build in the finished builds thread...........Woohoo! Then I will be able to comment on the lag (or lack of lag) situation.

phunk 10-05-2011 02:48 PM

dont worry its definitely a "lack of"! lol... every turbo car has a boost transition period, these turbos are still welllllllll on the good side of "laggy".

who are you going to have tune your car?
