Dirtymilkman Posted December 21, 2015 Share Posted December 21, 2015 My 1990 CH is completely stock. 4 valve E6 all stock parts. I put a new injector pump on a few years ago and we dyno'd it. It was 336hp to the rear wheels. I was curious if anyone else has dyno'd one? What realistic, real world hp are they capable of? I was told 400 is all the bottom ends are good for. Has anyone juiced one up and dyno'd it? Quote Link to comment https://www.bigmacktrucks.com/topic/43189-e6-4-valve-question/ Share on other sites More sharing options...
Motorwood Posted January 11, 2016 Share Posted January 11, 2016 We have one that has put 970HP to the wheels. It doesn't pull trailers though, just a sled.

Timmyb Posted January 12, 2016 Share Posted January 12, 2016 I reckon 336hp at the wheels is pretty good for a 350hp engine. Quote Link to comment https://www.bigmacktrucks.com/topic/43189-e6-4-valve-question/#findComment-319561 Share on other sites More sharing options...
theakerstwo Posted January 12, 2016 Share Posted January 12, 2016 Years ago when we had a dyno it was 23 % lost to the rear wheels.I know now oil is better and gears are made better along with tires so that is very go for a 350.I would say it got the fuel turned up on it.

GOOG Posted January 12, 2016 Share Posted January 12, 2016 Tough to believe a 350 is putting 336 to the ground. I would expect to see 18 to 20 percent loss. What HP is your engine?

GOOG Posted January 12, 2016 Share Posted January 12, 2016 What was cost to dyno? I'd love to have mine done. - Tom Quote Link to comment https://www.bigmacktrucks.com/topic/43189-e6-4-valve-question/#findComment-319622 Share on other sites More sharing options...
Dirtymilkman Posted January 12, 2016 Author Share Posted January 12, 2016 Its a 1990 ch613. We dyno'd it after we put a new injection pump on it in 1999. The pump wasn't turned up, the factory wires are still through the bolts. A Mack guy once told me that the 350 4 valve was good for 400 hp at the crank. I'm just curious if anyone has done different injectors or turbos on an e6 4 valve and what it yielded.
