Thumbs up Dyno Graph

Just thought I would share my dyno graph. Mods are in the signature.

Re: Dyno Graph

Can you reload the graph in rpms instead of mph? My graph does something similar to yours with my 1.7 scorpians and I think that they may be causing the power loss up top.

Re: Dyno Graph

That's the only graph I have of the dyno. About the power being low, I kinda got screwed on the heads. I bought them from a member here and he wasn't completely honest about them. Should have went with Lloyd Elliot. Car feels strong and I can't wait for the track to open up.

Re: Dyno Graph

Re: Dyno Graph

Stock gears? If so, it looks like the car is taking a crap at 5400rpms. That will probably hurt your track times.

Yeah, either that or he shifted gears at that point.

Re: Dyno Graph

Stock gears. I'd have to look at the video to see when he let off. It may have hit the rev limiter causing the drop. I'm pretty sure it was still making power. I wish it showed the rpm's on the graph. Guess I'm going to have to invest in new heads. What do you guys think the power should be? Maybe around 370? Thanks.
