Looking good. Looks like your max HP was right around 6050

Pretty sweet man~!

Did you record the dyno run on video? I love the sound of a GenV at WOT on a dyno. :th_thumbsup-wink::th_thumbsup-wink:

~F~

That thing SCREAMED yesterday!

Original post updated with video.

dang. am i reading that right. almost 10 pounds of boost at 6000k on a 3.4 pulley?? and i like the power curve. nice and smothe. does that not seem a little low on hp tho to be camed??

 

[VinnieGTP]

Well, humidity was 100% that day. There was a similarly moded Bonne there that dynoed within .5 HP of Keith's car. We all expected higher nmbers but it is what it is.

 

[blowfishRus6]

yea true. is that seriously 10 pounds of boost on a 3.4 tho???? HOW??

 

[blowfishRus6]

and can i ask what cam did the bonne have??

 

[VinnieGTP]

I'm guessing the L36 bottom end helped out

It was an S1x as well with gen v conversion and slp headers.

 

[blowfishRus6]

ahhh okay. dang compression. welp i got my S1x dyno results. now i need my XP results

 

[blowfishRus6]

and i must say the S1x has a nice power curve. looks like a good aplication for normal DD/street/track driveing

 

[VinnieGTP]

It's a favorite of most.

 

[blowfishRus6]

thats good to know. ive been debating between the two and dont know witch one to choose. everyone that has the S1x talks very highly of it tho so i think therefore i have my answer

So your 3.4 pulley on your setup is like running a 3.0 pulley on a L67 setup...

Nice run and whine!

 

[blowfishRus6]

i know right. imagine a 3.0 pulley....

It's not my car but yeah, pretty much. And that video got cut off for some reason, that was only to about 4000RPMs. I'll have to try to get a video of it up to 6000 for you :th_biggrin3:

We had a 3.2 on it and it ran the same HP/TQ number at about 11.5LBs boost but we had to lower the timing a little to get rid of knock that we saw. So we decided it was safer with less boost and a tad more timing and stick with the 3.4.

 

[blowfishRus6]

i was gonna say, it dident sound like it reved that high, 6000k would be awesome!!!

The second run on the dyno sheet is with the 3.2. You can see how close they were.
