Customer built his own car (from what i'm told)...I think Tim did some fabrication/welding on it and the tuning before.calvin wrote:i think that is timdogg's secret and let it remain that way
It was done on another Dyno Dynamics unit when the car had RC 1000 Low. When they failed from the high duty cycle's they replaced the injectors with Precision 1000cc and the FJO Box...like I said, I dont expect these to last longBugermass wrote:Looks really f*** good, especially since Tim said he did the tune on the street.. Bad ass job Tim..
Like 41-45 psi...as far as I know, these injectors dont really work/flow any more after 70-80 psi.Boosted K20 wrote:1000cc for real??? what was the base fuel pressure, like 80? lol
He told me that he never got to tune it on the dyno cause he tried to tune it when rom .63 was all messed up.. he said later he went back when calvin gave him a good version of .62 and retuned it completely on the highway.. Theres no exact HP to injector size value, alot of it depends on the effeciency of the setup, and how rich or lean the car was tuned, just cause static pressure was 42-45 doesn't really mean anything when its under boost. It depends on the regulator used, and what ratio the regulator is setup for... Most regulators are design to raise the FP on a 1:1 ratio in order to keep a steady pressure differential across the injectors as the manifold pressure increases, but some regulators are 2:1 or higher.. Also the duty tables are only acurate to a certain degree.. I've had injector duties go over 120-130% and still not run out of fuel. Although logically and mathmatically it may seem correct, but theres some variable there that doesn't always make it true.. Havn't figured it out yet, but I bet it has somthing to do with injector latency or somthing.. ANyways, just though I'd throw all that out there..xenocron wrote:It was done on another Dyno Dynamics unit when the car had RC 1000 Low.

Bad ass job Tim..Then he just cleaned up the differences in fuel on the street, no timing touched.

I just usually advise customers to stay away from overworking injectors for obvious reasons.
