Hot Cam dyno.

I am just beginning to get my car dyno tuned. It made 300rwhp and 300rwtq with a stock A4. It is full a full bolton car. I think it will make more power, the injectors on this run were defective and possibly only 19lb. The tuner could not get it to run correctly with the defective ebay injectors. I replaced the injectors with good stock ones and the tuner is going to give it a try today. I am hoping for 320s hp and tq.

Injectors are definitely a requirement. Hopefully, he can get it running properly. Good luck!

Stock injectors should hold a Hotcam, I have a set if you need some. Further more Hotcam A4's run 330-340rwhp and M6's can touch mid 350's.

This was as good as they could get, but I think something is wrong

Yes I noticed it works for me only. I can't figure out how to take a picture from my pictures and post in on this site, I can send the graph in an email.

Toss it on a generic picture hosting website. Photobucket, imageshack, or whatever then post a link to it here.

Was the convertor locked on the run...Ive heard of ppl gaining 30rwhp or so just by locking the convertor.

Yea, all depends on how loose the converter is. Some people claim locked converter numbers are inflated when in reality they are just more accurate.

I think I got it, only problem I have is the drop off at 5300rpms.
Not sure if the converter was locked or not; I will have to ask the them, but I would assume it was.

I cannot see the graph (work blocks those sites) but I would say that a 5300 rpm drop is commonly a valvespring issue (valve float, improperly adjusted RR's).

Just thought I would add my .02.
