Re: so this is what 500rwhp sounds like

Let me clear some stuff up here.

1) There is no problem with the truck on the jack stands. The truck is tied down with 8 tie downs and is more secure and does not move around because the front suspension is what causes the truck to move around. Please do not compare a very unfortunate accident with a floor jack to a set of jack stands.
(If you want to see scary see how a car on the ground moves around on a dyno)


2) The purpose of the dyno is to safely tune a vehicle without making multiple passes on the track or even worse the street. Oh and for the record we only spent 2 hours doing it.


3) Torque readings from a chassis dyno with a automatic transmission and a non lockup converter are wrong anyway.


4) If the front wheels are in the air or the propshaft is missing the dyno reading will be the same. I would bet since we are losing power in the viscous coupling it will actually make more power on the 4 wheel dyno not less. remember if you pull your front propshaft out and put your Syclone or Typhoon in park on a hill it will roll away....got it?


5) The only thing here that was getting abused was the viscous coupling


6) My pump gas street car on the same dyno showed 845 to the rollers. It went 9.21/148 @3600lbs so you do the math and then tell me if we have a happy dyno or not.


7) No matter how much power Don's truck makes He is happy and you guys should try to support him instead of bashing.


8) last but not least, Where I come from we race cars not dynos.

no one is bashing him bob...just giving him some shit. I was shocked to see that the truck didn't move at all even w/ the wheels in the air...just looked awkward to me not ever seeing that method before.

I bet the dyno reading is slightly less w/ the prop shaft in than out since you're driving those wheels.

I wanna come check out the new shop sometime...and i still owe you that beer/lunch from hooters years ago :tup:

if he brings his truck, now thats funny..

I'd be more likely to show up in bob's old syclone than renz is to show up in his truck..
and the syclone is in more pieces than I care to mention at this point in time. :tup:

Re: so this is what 500rwhp sounds like

My question about the psi he's running on the street tune vs race wasnt directed as the boost being to high for a built motor. It was more of a thought as why is that much boost needed on that large of a turbo? I would have thought with that large of a turbo and at the min a mild build it would take less boost. But I guess not.

(I'm just trying to get ideas on where my own build is going to stand hp/tq wise with the turbo in my sig, and what psi I will have to run to make power to suit my needs wants without having the money to fork out on a larger turbo. That was all.)

Re: so this is what 500rwhp sounds like

just so you guys know i dont have a huge bowtie motor i have a stock block, "plus 4bolt" stock crank, stock vortec heads motor. i have a cam, srp pistons and eagle rods "i think". 23psi is not a lot of boost and remember this is NOT tunned for alkey. we tunned on pump gas then turnned on the alkey for cooling. once i get some track times in and keep it together for a bit i will go back and do a full tune and spend some time with it like bob said this was a couple hours tunning for the new headers, ic turbo setup. i plan for some track time this week hope to see some good numbers.
