depend on a mustang dyno but they typically read low. This is at only 8psi and with a low compression piston he need to upgrade his injector before he can increase the boost. He's been driving/racing his car for a while and he also had a Vortech so if he say that his car pulls a lot harder at 320whp then it means the car is really making decent power. People are so hang up on the number.

 

Thanks for the support Athens......I really didn't intend to defend myself or the numbers as I have no intentions towards being a dyno queen. However, Just for some perspective.....As a coach for the Hyperformance driving school at Thunderhill I get to enjoy the speed and power of many cars that most people never get to even sit in. 320whp and 333tq on a mustang really doesn't mean much to me but I reported the numbers in order to be specific to the STS FI community. My "seat of the pants" dyno pulls like a C5 Z06.....I am stunned and pleasently surprised at how hard my Z pulls and just never gives up or starts to nose over. My build is perfect for me and my track use and should provide many many miles of trouble free smiles.
Again, thanks Athens for the informed perspective. Hopefully accurate information will reduce the dyno queen flammers.

i guarantee a properly running Z06 does not feel like a low 300 hp 350z.

My supercharged G was 460whp DD (with >375 ft-lbs at 3800 rpms) and was about even with my buddies Z06 at the track and from a roll.

Theres no way i could give him a 100 whp and say the performance was anywhere near the same.

Either way, for a hard run track car, that will be nice and safe and sounds perfect for your needs!

Check these Dynojet numbers of 366 HP and 350TQ. These numbers would be way less than my 322hp and 333hp numbers on a Mustang. C5 Z06's are fast but not nowhere near the C6 at 505HP. Maybe you ran against the C6......Before my car ran this good I could hang with or even pass a stock C5 Z06 depending on the driver. Your Dyno numbers only prove the point that they are good for stats but do not necessarily equate to real world perfomance. A comparison of Dyno numbers, Yours at 460/375 -- Vete forum at 366/350, would indicate your G should pull away cleanly but it was not the case. I have no reason to embelish my claims (ie posting my relatively "low" Mustang dyno numbers) but with over 30 years of racing seat time (yea I'm an old guy, 42) I can assure I am more than qualified to make my claim that my car does indeed pull "like-simular-equal-same as.......a C5 Z06.
BUT....more importantly, as you stated, it should indeed be safe and sound and perferct for my needs.

 

/\ so you have been racing since you were 12 yrs old? I wish you are in the North East so I can get pointers on how to drive ...lol

 

Yea....grew up in a family of racers (Motorcross, karts, desert buggies, cars) it was a good childhood for a house full of boys...... I got my first motorcycle at the age of 5 and started recreational racing by the age of 8 and competitive by 12 (MX and Karts). My brother went Pro for MX and rode the european circuit but I have never cracked into the paid to race category for anything. I went strictly cars (autoX and road coarse) when I had kids to minimize my bodily damage . Just grins and giggles racing now.....plus all the free track time with the coaching gig at Thunderhill raceway.

 

I hate to beat a dead frickin horse but, for some reason, this C5 Z06 thing has got me kinda pissed........mostly because I didn't want to "defend" the performance of my car. I would like to think I am mature enough to let this crap slide....but apparently not this time LOL. So.....here are some stats that support my claim other than my subjective "seat of the pants" report
-322 WHP on a mustang Dyno + 15% (widely accepted Mustang VS dynojet) = 370whp
-Add 10% to the 370WHP for drivetrain loss (conservative) = 407 crank HP
-A bone stock C5 Z06 rates 405 crank HP
-10% drive train loss for WHP from 405 = 365 WHP...within 1 whp of the Vette forum WHP.
-Conclusion based on good stats: STS 350Z on 8psi with light flywheel and a good tune = bone stock C5 Z06 in terms of HP perfomance.

Ok, now I'm done....Sorry for the rant. I am happy with my car though =)

 

alright guys im saving up to buy the sts kit for a while and been reading up in this forum so i want to know what are the most common problems that yall get from sts i have full boltons on my z its a 04 chromesilver z base model.

 

oh and i forgot i have the cobb accessport and wanted to know of anyone used this with the sts turbo kit as well for tunning

 

The main problem is hitting full boost on 1st gear. It may not be a big deal because it will help with traction. A good boost controller will solve this problem but other than that the kit is reliable. It wont give you that much of an extra room if you want more power without an upgrade on the turbo and FMIC.

Not familiar with COBB but if you must then I would go with Uprev before I go to Cobb. I'm not a big fan of reflash because it doesnt offer overboost fuel cutoff protection and no knock control on the higher rpm.

 

well i already have the cobb access port so im guessing nobody has tried the tune with cobb then? I hear they do good dyno tunes for turbo and safe tunes for your engine for day to day driving.

 

what are you running athenG? besides the sts turbo kit what else helped you with your turbo setup and how can i find out more info on the uprev? i heard the sts kits where having some kind of oil issue with up hill riding? is this true. thanks

 

I had Testpipes but now I'm back to my stock CAT and I'm running Water/Meth. There is no problem with the oil backing up unless you routed the oil return line the wrong way. I did have that problem in the beginning but only because the oil return line wasn’t routed the way STS suggested.

I have Utec and for me protection is everything. I can sacrifice some of the drivability but I want my motor protected as much as I can. This is why I have stuck with Utec. I was offered to try Osiris but in the end I stuck with what I have. I do my own tuning so Osiris doesn’t help me there either because it doesn’t have support for 3rd party Wideband which is important for tuning on the street. Unless you trust the OEM 02 sensor to tune your car. I believe even shop like Forged Performance still favor Utec over a reflash for boosted car on stock block. Overboost and detonation are both killers and you need an EMS that can protect your motor. Trust me, I have experience both many times and Utec was there to protect me. At one point I hit 10psi at 5000rpm (I'm only set for 8psi) when I was playing with a 335i in the Winter, and if it wasn’t for the Overboost fuel cutoff, who knows how much boost I would've gotten and probably have blown my motor at that point. When I'm racing someone the last thing in my mind is look at my gauges, and because of the heat of the moment, I'm going to be WOT the entire time until the race is over. The hotstart issue is not problem with me either, it start like stock 99% of the time. Unless you go with a bigger injector let say above 550cc then you should be fine.

Now let us look at the competition. I like my kit but if the cost to do everything is close to a PowerLab kit then I'll go with a PowerLab before I go STS. If the difference is only $1000 for everything then I'll go pick Powerlab.

 

well they offered me a military discount i think 10 percent or 5 percent but not sure anyways doesn't a utec come with the sts turbo kit package and the reason too is because the sts turbo kit is alot cheaper after that military discount no one else offers a military discount lol.. so a good deal on my side. so will all the bolt ons i have will that even do anything or should i go back to complete stock?

 

plenum spacers test pipes, high flow cats etc, will help

 

Yeah i have the kinetix plenum, strup headers, kinetix hfc, megan racing y-pipe, greddy ti-c exhaust, weapon-r engine dampener, ground wires, jwt clutch and flywheel, and the cobb tuner accessport. agency power pulleys stock size.

 

10% of what? If STS is giving you 10% discount of $6500 just for the kit then forget it. If you get everything installed and tuned for less than $6500 then that is better. Yes, STS come with Utec..


You have parts that is going to be useless or may hurt your performance with STS. Your Exhaust is useless, Y-pip and Headers may hurt your spool unless you do a jet-hot coating or heat wrap them.

 

the whole exhaust system is no problem i pretty sure alot of the z guys i know will want to buy some performance parts for cheap lol... but if it means getting bigger gains then thats what matter.

and the 10% discount was out of 6500 but i think he dropped it to like 5400 is that bad? if so where elso would i be able to get cheaper?

 

that is what I dont get... Fck STS if they think their kit is worth $6500. Add 500 more and you get a Powerlab kit that has a much better turbo and power potential. $5400 isnt bad but if you can go lower then it will be better. I think you can get the kit at $5500 if bargain enough and look hard enough so the price they are giving you not special and something everyone can get. Are you getting this from a dealer or straight from STS. Do you have a shop that have experience with STS?

 

Wow, $6500 I thought those kits go for $4800 or so.
