Thread: Went to dyno today

How high did you rev? And did the pickup work on your run? Andy and I didn't get accurate numbers because of this. It showed us revving to only 6700-7000rpm. I was hitting fuel cut and andy was revving to like 7800.

Get your self a set of S4, and a wideband. Minor adjustments and your car will pull like a freight train

i revved up to 7500 and the pickup was working fine when i dynoed

It seems like every year the pickup never works on my car. Last year I revved to 8k (according to the guage) which is about 7700rpm and I only did 260whp on 10psi. I wonder if I have been getting the wrong #s?

It seems like sometimes it works and sometimes it doesn't. But I would like to get some accurate numbers at least. The first pull I did showed only 26X whp. On 20psi! WHAT A JOKE! It showed that I only revved to 5600rpm! we took the pickup off alltogether and adjusted rpm to the drum and it was still way off. The numbers I got are so inconsistent. My best dyno on 15psi was 371whp and 18psi was 407 just a couple of weeks ago.

Andy, post your charts man. yours look a lot like mine.

Here is 15psi.

Here is 20psi.


And I hit my rev limiter on every run.

i dont have a scanner at this point, i guess i could take a picture of them

here is a pic and couple vids of my car

whats up with ur white gloves andy

Brody just dynoed his 300zx again tonight. He posted 560whp on 21psi at the dyno day. And made 604 today on the same boost. So it looks like the graphs are off by about 40whp, both for me and him.

Who knows, maybe your numbers are a lot higher than you think!
