The G35 has numerous times. My car did 13.97@100. Best speed was 101 but I think I'll do better in a week or so, hehe. I know a couple people have done better than that.

I thought I would drop this off here/for you so that you can take a look at the APS single and TWIN turbo dyno's.

Here are the dyno sheets for the Single Turbo 350z and Twin Turbo G35.

These are the Brainstorm Performance shop cars, the dyno is a DTS AWD dyno, highly accurate, and very repeatable results.

You can easily add 10% more HP to these results for "DynoJet" numbers, and sometimes more, depending on the setup of the DynoJet.



Also for anyone interested in getting detailed info, (someone may have already mentioned this, if so I apologize) Brainstorm is holding a BBQ, MEET, and Dyno day, and for your technical needs David (Senior Engineer) from APS will be present this Saturday 7/23 from Noon - Six.

The shop is open from 9:00AM-6:00PM should there be other needs.

Kinda' makes the ST look like the better option when you factor in pricing, no?

A TT will almost certainly pick up faster than a ST set up but if you are going to say a TT gives more torque than a ST setup, your statement is so general and so broad that it is misleading. The one thing that is correct and I'm sure everyone will agree is that a TT is more driveable as the powerband is shifted into the lower RPM range. You must realize though, for this shift to go lower into the power band, the turbos must be sized smaller, which ultimately gives up on the top end of the RPM range. Now someone else said that TT will ultimately give the most horsepower. That statement is such a crock of S**t as you can make the highest HP on EITHER a ST or TT and this is not G specific...only difference is that you spend twice as much money on the TT.

So from this guy's review, which Brian posted, the TT is superior in every way and he said the ST would be his pick after that, and then the supercharger. So please tell me what I said in my post that you said is absolutely not true and that somebody should delete my post??

PS - Go pick up SportZ mag and see what they review about the TT over the ST. The judges said that the Turbonetics kit kicked in for more of the higher rpm's while the TT kicked in early and was much more fun. They show you dyno's of all the kits and the TT's had torque curves very eary. Also pick up Road & Driver's Speed magazine that reviewed 4 turbo kits.
Once again, you are referring to someone's VERY broad and generalized statement. Any turbo company out there can easily size a ST to provide way more power by simply changing 1 turbo. When increasing the power on a TT kit, you have to carefully consider how large of a housing and compressor maps as they may not all be well suited for the G engine (or any engine for that matter). While in this case, the TT setups may be well made and thought out, I think over time, very promising STs will come out (like the APS).

Not to say the single is not a good choice because it is..but on a V engine it doesnt matter how you cut it.. the twins will spool faster. Anyone that disagrees bring a single turbo G35..I have the twin turbo kit and we can make a fair comparison.
For what the twin setup costs, you bestter have a faster spool up. Honestly, I think if someone did it right and made a new exhaust manifold that is more efficient along wtih a ball bearing turbo (correct em if I'm wrong, I'm not sure on the single setups available to the VQ market today), the spool up can be almost as fast and still be quite a bit cheaper than TT.

I dunno...The FD3S rx7s had sequentials. I had one and had a crap time with that setup because of the million vacuum hoses and there would always be one or two that wanted to crack or blow off causing a bunch of problems.

I said they have more torque down low. The torque curve kicks in earlier. Right now, if we're comparing kits available, which I thought we were, since these are our only options, the twins will definitely give you more hp. I'm not comparing twins and single turbo's on a supra, we're talking about a G35 here. In that case, yes, the TT kits that are available now will definitely give you more hp than the singles, that's a fact and has been proven. Now I belive SFR just posted the other day that they're working on a kit that has a much bigger single turbo and will be capable of much higher hp than the current kits. But again, there will be a lot of lag with that.
