Turbo's do not like exhaust

[silverpoison]

I am working right now and Greg just sent me a pic of my car. Its on the dyno now fully buttoned up with the exhaust etc. Only change done was now I dont have open down pipes and the car is on a slick compared to a street tire. Its down about 60-65 rwhp like this with the same boost as before at 19.7#

I've heard of sticky slicks eating 40rwhp on a dyno.....

Ok, I was wrong. They let the car cool and it made 671/608. He said he will send the vid in a while.

On a side note, I am using the stock over axle pipes and they are not bent with a mandrel bender, I may do later a custom exahust with cut-outs but for now is good. The car is also on SLICKS..... the first dyno tune was done on street tires.

slicks don't transfer the power correctly on the dyno..they grow.. I went thru alot of head scratching because of this on the SVO.. it was down a large anmout because of the ET sTreets... you can see them grow while on a run..

the car was on slicks because it may see some track action tomorrow and we wanted to verify that my air fuel was ok after we installed the full catback and other stuff.

My 60 lbs injectors are almost maxed out, need to upgrade but for now i cant.

you guys going out to the 'dale?

most likely, there is no cage on the car yet ...hopefully we get the car to hook and get a good timeslip before we get kicked out.

yea man i was told gear ratio (which would be affected by tire size ) and actually the tire pressure has something to do with it too , the more pressure the higher the dyno numbers

60lb injectors maxed at 700rwhp? Thought they could do more. I've seen 52's do more.

You have to remember I have a auto. That means I am making about 954 fwhp on a slick. We can raise fuel pressure, but that is not the right way to address pegging injectors.

ah got ya. that Auto eats up quite a bit up HP

 

[ChevyKiller]

Ditto - I maxed the #60's at 650 rwhp

Ed, sorry you have to work, but Greg will take care of your car. I'll be out tonight as well. I won't be running any juice and am just going to tune and dial in suspension on the blower tonight.

Did Greg send you the vid of my car? I made over 660 at only 13 psi!
