GUILTY AS CHARGED!!!!

Spun all over the place, as usual, but i trapped my highest ever, 85.11, iirc. fastest of the night was a 9.0x, and I had an absolute blast even so. Wish the guy with the SRT10 Ram had some more seat time, it would have been fun to have raced him all night

Thought you had a run in the 8's, the first one against the bmw. That was actually my buddy, he said afterwards he got to the line and saw the diesel truck and though he had it won, then he got waxed. Definitely would have liked to see you run against the srt10 a few more times.

man, the boards are shit down there for some reason, and they randomly flop the speed/ET display, so that was probably my 9.0x@85 run.

Dude made me proud launching that beamer hard!

He has a m52 2.8L swap in it converted to obd1. He weighed it over the weekend and without driver was under 2500lbs. A turbo is in its future but hes got to sell his jetski first to fund it. Quick car for what it is, trying to break into the 8's before the turbo though.

sweet deal, if i EVER get some slicks I should be dipping toward 8.2x or lower. Had an 8.6x last fall, hoping to cut my 60's from an average of 2.3 down to 1.8-1.9 range

So...I might be taking an '05 F250 with the Powerstroke in trade for my Z06. I don't really want it, but I think it's worth a little more than my 'Vette, and I think there will be a broader market for it.

^^^ make sure you get a chip that can disable the EGR valve (the cause of massive engine failure in the 6.0). I like mine a lot though.

for future ref:

- Source Automotive sells a nice kit (running that on my truck)
- Pure Diesel Power sells the Source Auto kit, plus a few more

FWIW, PDP's website is a good reference for cummins replacement parts, etc.

blower feeds big turbo, big feeds small turbo; there's a bypass valve on the inlet of the big turbo (that's why there's a second air filter) that allows the turbos to draw more air than the blower is pushing under certain operating conditions.

how much pwr? won't the big turbo's flow be choked in the little one?

I really feel like he's going to over rev the little turbo.

truck hasnt been dyno'd; apparrently it makes 1psi at idle and hits 80psi max


as for the turbo arrangement.... that's a conventional compound turbo setup. usually it's the turbine housings not selected properly that causes issue with tuning, not the compressor sides.

small turbo comp inducer usually runs 54mm (stock 12V) to 66mm, and big turbo usually 66mm (towing twins) up to 95mm

just like any centrifugal pump setup where one feeds the other you can imagine the difference in flow maps with the various combinations - usually a smaller secondary paired with a larger primary gives the most broad powerband

cool good to know... i guess since you are compressing it to 80 psi everything changes in the lb/hr even though cfm my be limited.

correct - it's all about increasing the total mass flow rate through engine

i know not everyone's a diesel gearhead, but some of the stuff that's getting churned out nowadays is eppicccc.


with that said, a roots blower on a cummins is a helluva noisemaker

scene? as in like people taking notice at an event - or scene as in 'engine bay'?



basically, you will not be having conversations with the passenger type of noise (there should be a link in this thread to one)

http://www.youtube.com/watch?v=Okn7MTZ0OWA

that was one if the same guy's first iterations




To be honest, wtih no firewall insulation and a 5" stack behind the back glass on my truck, any driving condition save for downhill coasting requires yelling to the passenger

This is how it feels to be strapped into a prostock diesel truck (this was a shut-down run, but we're talking sub 5-sec in the 1/8th)

...easier for the masses to understand as an "amount of power over stock". I have no idea what the CR injectors are


mine... 5x.014" orifii, +0.010" pintle lift, 280Bar pop-pressure ... 'industry' rating is ~140hp. iirc my stock injectors were 5x0.009", something like 240Bar pop (shooting in the dark)
