DR750's V1 guess the dyno

[kywhitelightning]

Since I feel the cat's out of the bag already I figure I'll add this to the thread, especially since the dyno day is getting close and the weather has done a complete turn around (probably because of Nate's optimism lol). The forecast will be nearly perfect as the precipitation chance went down to 10%. A high of 66* will also favor good power (I'm hoping it'll get into the 50's but I doubt it will).

The weather was more cooperative tonight. This is a temp and baro corrected graph. Still pump 93 + 1600ml/mil injection rate of pure M1. 69% IDC up top with the gas. I doubt I will run out of gas on the dyno but I have a BAP and lots of room with the AFPR. Like I said before, when the weather is right, this car is a freaking blast!!!!!! During this pull I logged airflows in the 650g/s area on my translator logger and was just a touch over 4700Hz seen by the ECU. This also pulled 2* of timing away up top but didn't trigger the CEL. With C16 even in the 100* heat this summer and this timing map, it never showed 1 count of knock and poured the timing to it so I am confident the race gas pulls will be crazy.



This is the UNCORRECTED version of the same run. This is why I have made posts on this board discrediting the validity of Virtual Dyno using the DynoJet correction factor. Although, when you input the weather variables it brings the graph to where it should be IMHO. Here is a fantastic website I have found to get local weather information past tense so you can enter this critical data into VD to get IMHO believable graphs. Weather History for Columbus, GA | Weather Underground Enter your city and the date in question and it gives a 24 hour chart at the bottom which contains everything needed for VD. The baro makes a huge difference for all of us that are fortunate by being near sea level. Enjoy this FALSE graph ha ha.

I don't dispute the numbers, since they seem in line with the hardware. The curves look pretty unrealistic, though. Power continuing to climb past 7000RPM, and still making almost 500WTQ in that range is not a trend you will typically see with stock cams.

Yeah try not to get your hopes too high.

I stay grounded and I believe it'll be somewhere between 590-610 on pump + meth weather permitting. The reason I posted this chart is to show what GOOD weather does for it. Like I said before on the first chart I put up, the weather then wasn't great but familyman wanted a graph and I drove the car that day. The weather was good last night and it showed. Funny thing is that you didn't disput the way HP stayed on the first graph and it followed the same trend as this recent graph but because the numbers were higher you claim cams won't let that happen. This motor whether it's the tune or the hardware 19T's or the 750's has always seemed to make less TQ than HP but holds TQ deep into the revs which delivers good HP numbers.

Dyno day will tell the story and I'm sure even then there will be skeptics because Matt or Ray didn't do it.

screw the naysayers..don't worry about them. To even have something close to a well built and reliable 600whp 3/s car is a feat in itself...ask me, I know..

Not sure who you're referring to, but as I stated, I don't dispute the numbers -- I think 6xx should definitely be attainable based on the build. I do, however, think it's unlikely that you'll be making close to 500WTQ at or above 7000RPM as the log suggests. I think that might be a first for any TD04 setup...

Oh its not you.. People gave him shit back in the day on the forums..I was referring to that...

I've got cams and although I don't think I'll hit those peak numbers due to having different turbos I wouldn't mind that kinda powerband myself...hopefully we can make good on a well designed intake plenum..

I honestly hope it'll be the first to a couple of different sets of statistics. I haven't ran race gas in it since the weather has cooled off and truthfully don't have a clue what it will be capable of. It is cool to hear some of the opinions out there and I don't recall you joining in on the fun. Care to add your thoughts/guess?

when I dynoed my car, the wastegates were opening and I was loosing my boost, from 30psi+ to 25-26psi, that would explain the drop in power in the higher range.

This is where ECUboost will change the game...
