V8V dyno run

[V8Andrew]

My car had previously been dynoed at 370HP before modifications. Since then myself and the previous owner have replaced the air intakes, manifolds, cats (200 cell), back box, and custom map. Work was done by DAE and both Dyno runs were on different independent dynos. Ideally it would have been the same Dyno on the same day, and today was particularly hot which probably didn't help. In any case I was pleased with an additional 28HP. Video below

I also added some stickers for the GP this weekend - anyone else going to silverstone?

I'm attaching the graph for ease of reference here.

Mike your observations are interesting, and thank you for the clarity on the correction factor. I'm not sure why the test stopped where it did, certainly the limiter is higher than 6750 quite a bit. The conclusion is either they didn't run the test properly, or something is retarding power at the higher end of the revs. I may take it somewhere else for another run, certainly if it did make 425 as the graph interpolated to the redline would suggest it could, that would be nice! The wheels are Projex circuit 20s.

Thanks for the various responses. I've dug out the previous dyno chart below:


This shows a similar shaped curve to the other standard chart posted, and also shows power rising up to about 7,300 or so. Difficult to know whether it was the dyno/operator or something on the car that caused the tailing off on my more recent run. I'll probably take it to a different dyno and rerun the test.

Well I ran the car on a different dyno, and frankly was very impressed by the professionalism of them explaining everything to me as they did test runs on the car and etc. Certainly felt like a more professional operation called Dreamscience in Hull. The graph is attached below. As you can see the graph continues on a similar trajectory as before but this time all the way to 7250rpm where the test was stopped. I think my limiter is at 7300. The result was 406 which is a gain of 36 above what it made before the work was done.
I'm guessing that the conclusion is that the dyno run I did before was flawed. Both times I've been running tesco momentum fuel.

I'll do a video at some point.
