Stroked and Blown VT

What boost you got now and at what RPM? How was the tune done, Kalmaker?

Im not sure how much boost its running, i've got the feeling im running the stock pulley there was only one pulley that you gave me.

I didnt ask how the tune was done either

 

[Raptorsc]

Actually I gave you the high boost 61mm pulley straight up

And it seems I must have slipped another flat torque into the box before I sent it to you hey crikey yours is flat like the rest of em.

 

[MaN|aC]

yeah nice flat torque im just looking at my old dyno sheets when it was stock and stroked

The red lines was completely stock, the blue lines was the stroker

 

[Raptorsc]

OK, that would be interesting for me also, what was original torque curve like

 

[Raptorsc]

N/A yep they start off not bad and just drop and drop. Suprisingly or not suprisingly the both curves are the same shape. What cam you running?

A huge difference between 2100N (stroker) and about 3950 (blown) at the end of the RPM range , thats near double

 

[Raptorsc]

Did you run the quarter with the stroker engine?

 

[MaN|aC]

# CSBR-416 which has 216/220 degrees duration intake/exhaust @.050" and .493" lift on both. Ground on 112 degree lobe centres.

15.7 down the strip with the stroker
