Anyone pushing the T4 60:1 in the Turbonetics kit to it's max of 15psi yet? Any dyno numbers for this boost level?

Modified Mag went to 14 PSI...

 

Whoa! Thats alot! Be nice to hear that spool and blow-off.

 

Any numbers Rob?

Can anyone post the dyno to Modified's Z? I am getting ready for my F/I plans this winter. I found a great deal on the classifieds for a TN kit not too long ago...but now it seems like I have decided to take it further and build the engine to make around 500-550whp.

Im just interested to see the TQ curve they are getting in the maximum effeciency ranges of the 60-1. If TN doesnt hurry up with their stage 2, I might just consider another kit.

C'mon Turbonetics...hurry up with the R&D guys I need my motor done before next drift season.

 

Heres all the info on Modifieds Z.

 

Am I losing my vision or is there no info on that page? All I see is two posts, one that says "check out the new modified mag for info on the turbonetics kit. I'll scan the article later" and then taurran saying "great publicity for the turbonetics kit".

I see no numbers and no article scanned...

 

I can see it fine....The files are attachments on that thread...

 

Nope ...saw what I saw....no info

looks like about 450 rwhp / 511 rwtq. i keep thinking the piping on the TN kit is too small and will become a major restriction at higher than stock boost levels. in the graph, the engine is hitting 400+ hp by 4500 rpm and then gets up to 450 hp by 5000 rpm, but then the hp just stays there and then starts to ramp off.
To me, that looks like the engine can't get the air out fast enough...like the exhaust piping is limiting the engine.....what'd ya think?

 

I made 410 rwhp corrected on a DynoDynamics dyno @ 9 psi with my Top Speed 3" exhaust. I think I can make a minimum of 475 with the addition of my Alphawerks headers, AAM plenum spacer, and 15psi. That exhaust in the magazine articcle is definately more restrictive than my Topspeed or a single 3". The higher you push the boost the more important the exhaust system becomes in making power.

Couple things. That Z had the stock manifolds and a DC Sports exhaust. So 2.5" piping and stock headers. Not exactly the best for air flow.

 

I'd reckon your thoughts are about right, that's one of the limitations with a single turbo package on the VQ engine.
