What is Vortech's flow rating at max impellor speed for the T trim? How high are you winding the 377? That thing must be making peak HP at 7000+ RPM. I know each time mine is on the dyno, it continues to climb past where I have the rev limitor set (6600 RPM). That sound of the car on the dyno is unlike any other sound (horendous noise!!!).
As for the ASM unit, does it come in that GM blue color that is shown on the website. Does it have Arizona Speed & Marine CNCed into the top? Can I machine the logo off of the unit? Are there no provisions for putting the factory "TPI" logo back in place? I really like having these "stealth" pieces still on the engine.
Thanks in advance for your responses,
Aaron

up until two weeks ago, I was only able to rev my car upto 6500 or so rpm. I was floating the exhaust valves big time and this problem took forever to figure out. I felt it was pointless for me to try and figure out what my max rpm and flow rate of the SC when all I could see was 6500rpm. I finally fixed the problem by switching over to the comp. beehives and TI retainer. Now I have spung it up to 7800rpm under DFI datalogging(Only 7200rpm at the tach) and it is still pulling a bit. Max boost at around 7500rpm is 13psi. I think max rpm for the blower is 60,000rpm ( have to double check) and max power for the motor should come at no more than 7500rpm.
i have a dyno tune session scheduled after the first week of Jan. so I will know for sure.
The AS&M TB plate can be removed and I am pretty sure you can use a stock TPI plate. No, its not blue it is all billet aluminum.
Thanks for the reply. What RWHP are you expecting? I have no way to begin to predict without the blower flow at max engine RPM. Do you feel like you have the tune "spot on"? What AFR are you running when you hit max boost, what is the timing as well? Are you running the factory distributor/ignition?
As for the Monoblade TB, the following is the pic directly off their website.
If that is the only way that it comes, I will need to do some machine work for it to look right on my car.

the picture is not coming up? I will go on their website and look at it and tell you if that is what it looks like.
As far as rwhp I say over 550rwhp without nitrous and probably close to 700rwhp with nitrous. It would be hard to get a good read because I have a non lockup converter. the most I have dyno'd before with the 355 and 150shot of nitrous was 508rwhp and the power feels way beyond that by at least 100rwhp but I don't want to be too wishful. I have not used the nitrous at all because so far I am driving it on my own tune. It feels ok but won't know for sure until I see it on the dyno. I don't have the wideband option so I don't know what AF I'm at but the target is set at 11.5:1 under boost. My timing is at 30 degrees under boost with my alky injection.
I am running a DUI coil, distributor and MSD 6A box that's it.

There ia guy who did some testing years ago as did i and a few other on the 58mm. This guy had over 400CI and was making just under 500 at the wheels. He should a repeatable jump in hp every time he went to a bigg TB. I want to say the decided reason was less pumping loss's and they could be seen on the MAP sensor readings.
I my self showed a 20+ RWHP gain going from a 48mm to a 58mm TB. I was only making 320RWHP back then
Thanks,

i think you are pushing more boost than I am right? I am seeing 13 psi max.
We are probably running close to the same amount of boost (psi wise), but I would bet that I am pushing considerably more airflow with the R-series blower. It just doesn't show up as boost because of the "massively" reworked intake and heads, and maybe a bit to do with the cam as well.
However, you have to deal with more stringient emission requirements in CA vs mine in TX.
I'm still waiting to see some nice pics of the MB with removeable TPI plate.
Thanks,
Aaron

The plates MAY be a different pattern but is easily hiden

The Unit I sold was an old TPIs. All the old ones were just converted Stock TBs and did not have IAC ports
