Hey guys,
I'm not sure if one of these exsists already, but I'd done a search and couldn't find anything...I thought it would be a good idea to have everyone thats dabbled into Forced Induction, with Superchargers or Turbos to give us an update on their progress...You can put information such as, the Product name, how many miles you've put on it, what the dyno numbers look like, 1/4 mile times if you have them, and any problems be it minor or large that you've run into with the application....This might give everyone looking into FI a good starting place to reference information from...O and if you'd like add in what your total costs have come to for the application your running...Unless you feel thats to personal, which is understood...Later guys

 

OK,

this issue has been debated a lot. Let me make a suggestion. Why don't you run a search on Vortech and ATI superchargers. There a couple of guys out there with Greddy TT's and one PE TT (one more coming - from yours truly).

However, since it's 1:50am and I am done studying for the night, I will recap what I know about TT's. Guys like Steve (zimbo) and Ed (Eagle1) can weigh in on the superchrgers as they have th Vortech and the ATI (respectively) and they are extremely well tuned (Steve and Ed know what they are doing)..

I should say that the info below is based on what the my350z.com guys' experiences, but I will try to estimate what your times will be on a G (200 extra lbs).

Greddy TT:

Cost: $5900 + $1200 + $500-700 (parts, labor, tuning). = Total: ~$8000 (with tax/shipping).
With around 6.5-7psi (what's possible with the stock kit) you will be generating ~340 whp on stock cats/exhaust - and upwards of 380 whp with test pipes, good exhaust, and good tuning. A well tuned kit with an ideal driver - high-mid 12's are very doable.
Note: From what I have been seeing, the automatics do VERY well (sometimes even better) than sticks because the AT gear ratios are not as aggressive and better traction is possible when you get into the 400-420 whp range (my magic number - 400 whp). One 5AT 350Z guy with an ATI procharger with upgraded PE 380cc injectors 9see below), fuel pump, and an FPR, pulled 411whp at 9-10psi and a time of 12.2sec on drag radials, so you can see that good times are possible.
Another note: If you want to boost over 6.5-7psi dafely with the Greddy kit, you will need an upgraded fuel pump and a FPR (not included in the kit). The good news is that these can be had for $100(pump) and I believe <$400 for an FPR (zimbo , am I right?), not TOO TOO expensive.
Do not forget, you will be losing your front bumper (the actual thick aluminum brace) if you g with the greddy kit b/c it is the only way to fit their intercooler - a big no-no for me.

Power Enterprise TT:
Cost: $6800 + $1200 + $500-700 (parts, labor, tuning). = Total: ~$8900 (with tax/shipping).
The times will be very comparable... no concrete claims can be made as very few people have the kit 9mine is stuck in customs over the last few weeks). The PE it uses FAR better quality components. IMHO this kit would cost far more than it does if it had the same markup as Greddy puts on their kit (again - this is my opinion - no flaming). Back to the facts. PE comes with a lot of extras - a superb oil pan w/ cooling fins that adds ~1 extra quart (1 liter exactly) to the oil capacity - bette oil "wear". PE also uses slightly lighter - far better suited turbos (PE 1420) that are ball-bearing turbos as opposed to Greddy's sleeve type. This results in a car that has essentially 0 turbo lag - i have heard from those who have it - that you can hardly tell that it's a turboed car. PE also comes with the best intercooler money can buy (ARC) by Greddy's own admission. The FPR and a high flow fuel pump are also INCLUDED (this alone equates the costs of the two kits). Also, it comes with the superb PE 380cc injectors that are designed specifically for this car - they just plug in. With Greddy, you have to cut the fuel injector wires to fit their RC injectors.

Another important point, with greddy you need to install their e-manage system (included) - which is less than on par IMO. You need to cut into the MAF signals, which ther piggiback computer "intercepts" ... I am personally not too comfortable with this. With PE, because they use Nissan/Infiniti-compatible injectors, the native ECU controls the whole system. If you want to boost higher - all you need is the correct TechoSquare flash to retard timing...

Hope this helps

Gurgen, With the Power Enterprise TT do you need to take out the aluminum brace to fit it cause I was thinking about saving to get it, but if the bar goes forget it. I'm too young to die.

Inside my shell, I wait and bleed

I would not get the kit if it necessitated the bumper removal. It fits behind and below the bumper brace - which is where all ofthe air flow is anyway

 

How do you set the actual boost level with the PE kit? Do you change wastegate springs or is there an electronic controller like the eManage?

Does the ECU reflash come with the kit or is that an additional cost? If the former, how does that work--do you get a coupon or something?

I've done a lot of TT investigation and the PE kit looks quite good. I can't get past the structural integrity issue of the Greddy and when I called the SSR Engineering guys I got a strange feeling (sorry I can't quantify that)--although I do like the fact that their kit uses the R4 software for tweaking.

My only issue with using Technosquare for tuning is that every car is different and unless you're right there it's a HUGE pain to do the iterative tuning process.

I agree with you on the differences in every car, but it really is not that big of a deal in this case. We are not running that mch boost here, and up to abou 5.5-6 psi, you do not even need a software upgrade - as the higher capacity injectors make the car plenty rich in open-loop operations(10.5-11 afr). An extra margin of safety and higher performance (i know, these don't go hand in hand) is achieved with the flash: retarded timing at the high end, mixture set to mid 11's for more power, and the usual ecu upgrade benefits.

Boost control - acievedwith any aftermarket boost controller. I will be using the HKS EVC V, the best there is with a VERY precise pressure control. But you can even use an old-school mechanical boost controller if you wanted to. The actuator spring pressure yields 5.5 psi - lowest boost setting possible.

ECU reflash is extra ($600 i think) - and in fact the official line at PE is that the reflash will void your warranty on the kit (12months).

BTW - I would definitely not do SSR. PE has really doen theirresearch - very well sized turbs, excellent intercooler, etc - SSR uses generic parts all around and costs about a grand more than PE on the street.

You know what? Let me stand corrected on that... You are as **** ofa driver as I am and would want the car to be perfectly tuned. Given that you are out in the east Steve, it might take you several tried to get it dead on perfect ... that's just the way it is.

Gurgen

 

What I've thought would be cool would be to do with the PE kit would be a TS reflash for 8 psi (if you're gonna go TT, might as well be really fast) and then use an inline fuel pump and an SS box a la the Vortech kit to do fine-grained tuning. If I get bored with my current setup--a very likely happening--I may try that.

--Steve

 

PE also does the ECU flash. I would assume that it would be better to go through the company that made the TT to get the ECU flashed. I don't know what they would charge. I will find out once I get back home. Also, the FMIC fits very nice behind the metal brace. I will post pics of the car, I wish i brought my camera when the car was on the racks, I could have shown what the turbos looked like installed, the pictures will only show the FMIC and the manifolds, etc. no pics of the turbo unless i can get it up on the racks again. As I heard, with the low loost no tuning is really needed, the bolt on is satisfactory. The ECU flash will probable make the acceleration alot more responsive, but will not know until I actually drive the car and feel the difference. What I might do is purchase another stock ECU and do some testing on a stock ECU versus a flashed ECU.

 

gurgen, i hope you get your kit in soon, and i can't wait till i get back to hawaii to take the car out for a long drive. Also, will post up the dyno stats and 1/4 stats.

 

Zimbo... that IS what I will be doing... I will tune for 8 psi but run the car as a daily driver at 5.6 - 7psi.

mdnt... PE does not do ECU upgrades ... it is way too involved to be done by anyone other than TS. Their closest competitior - JWT - hasn't even figured it out.
