So now I am officially a member of the 200+ WHP club, but I just squeaked in there. Finally took my car to a dyno and got the WOT stuff sorted out. Some may be disappointed with my results but I am not. My spoon header, stock intake manifold and throttle body are the likely reasons I’m not sitting at 210+ right now. Knowing these limitations I’m pretty pleased to see numbers around 200. My old engine with the same external bolt-ons made 178.

A big thanks to Nick at -------- who ran the car on the dyno and helped me out with the final adjustments.

An SMSP header is definitely on my short shopping list as well as a couple more goodies; however, I’ll have to wait until all the Expo bills are paid before I dig into the wallet again.

Here is the graph:


And a few pics (not taken by me) from my shake down lapping event I did a couple weeks ago… the car is quick!








Thanks to everyone who helped me through this. Special nods go out to Skunk2, King Motorsports, PIC and of course my builder Gord Bush Performance.

 

good job. whats up with your driver side door?

 

That is an awesome set up you're running! I love it. Congrats, the numbers are great.

 

nice numbers doug! congrats on the outcome. just a question tho, i could be wrong, but it looks like at 8500rpm power starts to fall off, but your revving to about 9100rpm. is this because of the stock IM and TB?

if you were to get the SMSP header, TB and IM would that flatten out the drop from 8500-9100rpm? not ragging on your setup or anything, just curious.

 

nice numbers doug!

 

nice numbers... and the car looks amazing

 

Thanks to the guys who stole my seets back in 1999 I had to have it repainted. Unfortunately under some lighting conditions you can see this effect. Oh well...

Fuzz, the internals are rated for 10,000+RPM so I'm not very concerned about reving it 9000. I was curious to see how sharp the drop off was so that I could optimize my shift points. Looking at my graph it looks like shifting anyware from 8800-9000 RPM will keep me in the top of the power band.

For sure an SMSP header, larger TB, and different IM will raise the peak power a few hundred RPM and likely net me 10-20WHP. Of course it would follow that my shift points would change with it which is why I wanted to build the engine to handle 10,000RPM.

 

nice numbers man , i never heard about your seats back in the day that kinda sucks.

 

damn very nice numbers doug

 

Good stuff! What numbers were you expecting to hit though?

 

Nice numbers man

 

i see, so basically, even tho your power is dropping off after 8500rpm, you sill push it to 9100; that way when you shift you'll be in a better spot in terms of the power range for the next gear....right? :wtf:

 

Yes! That is what I'm talking about. Here is a little image I put together to better Illustrate my point. Many people believe that the correct place to shift is shown in area A. For simplicity I've assumed that the revs drop 2000RPM when you shift gears. But look what happens when you shift at a higher engine speed.

Notice that the area B > area A.

It is the area under the curve that translates to vehicle speed and acceleration. All other things being equal the greater the area the faster the vehicle will reach the end of the gear (and hence accelerate faster).

 

AH HA!!! i have the seceret and im gonna use it when i never go to the track lol...........cuz my car is slow and old

 

ahh..wr3d, i got cha. kinda like shifting and still being in boost.

 

great way to explain shift points. +1, it also depends if you power shift. if you power shift you gotta do it earlier

 

let's see those boosted numberssssssssssss



area under the curve...sounds like a job for integration

 

How much do they charge for tuning?

 

Good job Doug.
Man, that bay is STILL cleaner than my dishes.
