Your car is bad ****! Good job!

 

kc's car is definitely the best looking on this site.

Hopefully someday mine will be at that point.

 

Why don't you just make a debris shield so you don't lose more money? I could measure and make the one that came with my APS kit out of steel (sheered and pressed) for around $75 locally from a sheet metal place, just have to drill holes....

 

With a T67 Turbo i think the kit would be good for 500-550rwhp on a built motor.

 

Thanks man, I appreciate it.

One other thing about the Turbonetics kit....I'm going to be looking for some heat shielding for the hood to try and protect the fiberglass and carbon fiber. It does get pretty hot under there. It definitely hasn't caused any problems yet, but I'm concerned about the long term effects of the heat on my hood. I don't want any cracking, separation, etc. Despite the "nose hole" in the bumper and the vented hood, that sucker gets HOT!

 

More then that buddy....I think Turbonetics is hooting for 700s with a T66 when Brad's built motor gets put in...

 

I don't think its going to be in the 700rwhp range unless they want to use a T70 or T76 turbo. LS1's using T67 with .91 A/R or around that number turbo are having a hard time reaching 550rwhp let alone using a T66 turbo. The T60 with .86 A/R turbo on LS1's are maxing out close to 450-500rwhp pushing 8-11psi max and the T67 are going to 550rwhp maxing out around 13-14psi.
I would love to see someone get over 550rwhp with a T66 on any car or setup... That would be awsome, but i dont think the Turbo is enough for that amount of power.

Im really thinking about a M35 with TS T66 turbo or even the current kit. That would be an awsome daily driver car.

 

Thats interesting I know Brad was saying that a 60-1 running in the 15-20 PSI area would make well over 500. Last time I was up at Turbonetics he told that when his built motor went in he was going to jam a T66 in there and make in the 600s and push for 700s. All this of course being at 15-20 PSI...

Edit: I just saw you said that you were getting 450-500 on a T60...I think Speed Dreams said they were making likw 420~ with the 60-1 at 14 PSI....Another 6-8 PSI should get you to 450...and the 60-1 is a bit smaller then a T60 IIRC.

 

In order to mount it I would have to make it the width of the car.....because there are no mount points anywhere in the middle. As well, there are no front mount points for me to attach to..including the engine cradle like in the coupe and 350Z. That sucker would weigh 100 lbs in the size I would need to reach the necessary solid mounting points.

 

I was giving the LS1 as an example because i have seen V8's running T60 turbo in real life. The highest i remember was really close to 500rwhp.
Psi is just a reading of restriction at the manifold so if we used the same turbo on V8/V6/I4 u will notice that a V8 will max out the turbo at lets say 10psi, V6 at 14-16psi and I4 at 28-30psi. This is due to the fact that a larger engine or displacment will take more air in than the smaller engine hence the lower reading of psi even though sometimes they produce almost the same numbers when they max the same turbo with the advantage going to the larger engine due to wider powerband.

Also in turbos you can't say 1 psi= 10rwhp because it changes based on where you are in the efficiecny of the turbo. For example we built a EVO that made 460awhp with 29psi and only made 472awhp with 33psi which means 3whp per psi while the same car pick up 10whp per psi from 21psi to 29psi. So when u are close to maxing out a Turbo dont expect to gain the same amount of HP per psi as you did before and in some cases you will see less HP due to more heat.

 

Oh I understand this I'm just saying that this particular application appears to be running slightly higher numbers then you are stating for the LS1 when it comes to power delivery from boost. Theres any number of reasons for this. As for maxing the turbo the 60-1 is not exactly maxed at 20 PSI but its close...I haven't myself tested this I'm just going on what Brad and Jhame from Turbonetics told me in regards to power output. We'll find out soon enough though.... BTW I've never really been a big believer in the 1 PSI= 10 HP thing...there are way to many other variables involved. Perfect example is my car... At 9 PSI my car makes 390 RWHP...thats a 150 RWHP increase from before the turbo....The 1 PSI/10HP theory would say my should only make 330. But it doesn't....

 

That was just an example.... My car gained 22rwhp per psi. Some cars gain 15rwhp per psi. As you said too many things gets involve, but i was just giving u an example to show when u max out a turbo even if u can get more psi u wont see any or slim gains

 

Oh I hear you...Especially as you leave the compressor efficiency island or get to the outer points of it...I haven't mapped the pressure yet but I think I'll do so tonight and see where this motor would land at lets say 15 PSI on a T66...this should at least tell us how well/or not it would react at that amount of pressure on our motor...I was mainly basing my power hopes on what Turbonetics said they had calculated as well as the fact that this motor seems to respond VERY well to boost....

 

Has anyone heard of someone using the Turbonetic's kit for less than 8psi.....say 5 for example this is what im looking into...... i want about 320WHP........for now......

 

That would be interesting to see.... Post the results

 

That 390 sounds pretty good... 400 to the wheels seems like a good round figure; would 9 psi be safe without other mods? And what would the T66 upgrade offer in terms of add'l power, and what would it cost? I'm just trying to get the maximum power for the minimum cost and danger to my car.

What's a built engine, what does it offer, what does it cost? Does anyone offer bored VQ engines for bigger NA performance as a starting point?

BTW, thanks to all those posting feedback. Keep it coming! I'm really leaning toward Turbonetics since I found out the TT kits cost $7500-7900 + $2000-2500 for install and tuning! OUCH. If I can get 90% of the performance at 50-60% of the cost, THAT'S my kind of deal. I don't need 1000 hp; I just want to feel the performance of a supercar (0-60 under 4 sec, 1/4 in the 10s), and the ability to beat 99% of all cars out there off the line to 60 or 80 mph.

LS1, the M is a SWEET car! I never thought I'd seriously consider a sedan over a roadster (though the Z Roadster is winning). I was just going to tell you to get an M45 and be done with it... but then I saw the M35 AWD (no M45 AWD)!!! Now I see what my wife's next car's going to be. An M35 AWD w/ a Turbonetics 450-500 hp! Forget the M45. Yeah, baby!

Redline... WHAT ARE YOU TALKING ABOUT?!? LESS power? I don't think we hear THAT one much around here. I'll take 500 rwhp if I can get it at a reasonable cost and low risk to my car.

kcobean, your car rocks. Mine will be stealth, but props, man.

Only reason less is cause of the clutch dude................unless u want me to put the angry angry ceramic dual disk in....but guys thats asking so much.........

 

Turbonetics has tested the flash up to 9.5 PSI in house and found that to be safe. At 9 PSI the car makes 390. Another .5 PSI should net you between 5-10 hp gain to the wheels based on gains seen currently by upping boost. It would be safe but trust me when you drive the car at 380 I think you'll see its got plenty of power. Of course if you are really interested in doing a T66 you would contact Turbonetics and they can custom design you anything you want and work with you on what is included. They are even currently working on the 550cc drop in injector upgrade anf flash so they might be able to include that as well....

 

Thanks, MiaPlaya. I think I could be happy with 390 to the wheels, but like I said, 400 is such a nice round number.

What would the T66 do, and what would it cost?
