I have one of these turbos ready to go on so I would like to see it run correctly on the Dyno Dynamics in Shoot44 Mode where CF and other parameters are locked down and I can also see the AT: and IT: numbers at the bottom of the graph charts (Ex Dyno Dynamics Dyno owner)

 

Well FWIW your results are VR dynojet...I don't have numbers like that but theoretically they are only slightly over what you are making. I'd bet that adding a BAP and making sure you had the pressure-relief mod done to your walbro would be nearly enough for your car on e85, might consider doing a fuel rail at the same time...there is a restriction somewhere in the standard X fuel system and I'm not sure where it is, but you should be able to run 30psi on your setup.


Sorry for the confusion, I have the 40amp single pump version.

Go for it. I have nothing to hide, look at other dyno plots from this dyno, stock cars make ~230whp, tuned pump gas stock turbo (evo) cars make ~300whp, e85 stock turbo cars make ~350whp, and fp blacks make ~480-520whp. This is your typical low-reading 1.0 CF dyno dynamics dyno (as stated). My drag numbers back up my dyno numbers, real world factors considered

 

Congrats Scheides! Looks like a beast! Looks like Shane did a awesome job!

 

Go for what?

I merely asked for a graph of the car run correctly on the Dyno Dynamics in shoot44 mode? Shoot44 is the correct method to run a car on that type of dyno, I like to see figures based on that so i make valid comparison to the dyno dynamics results here in the UK.

I dont doubt the capabillity of these turbos or I wouldnt have bought one for my own car

 

Heh I was just saying that if you want to see what a BBX does on shoot44 mode then it'll probably have to be your own numbers. I'll see if I can get them from DB Performance but idk if you can go back and convert a 'regular' run to a different shootout mode, I'll ask him. I urge you though, be careful looking at corrected numbers, it tends to get a bit silly. This is 1.0CF, I listed what other cars with various mod levels make on this dyno and that is exactly what you should do on your own. Comparing numbers between dynos and expecting results to be more accurate than about 5% if officially bench racing...I gave that up last year

2010 Bench Racer's League

 

It's true you can't compare numbers between dynos, or even between different days on the same dyno. So, that's where your comment about CF does not make sense. Surely you don't expect your exact car to have identical numbers in July and January? Or when it's hot and humid vs cool and dry? Or, to compare a ballpark number for a car at 200 feet above sea level vs one at 2,000 feet?

 

Nope I sure don't! A dyno run is a snapshot of the car in its current state of power output. Temp and all other variables are fine, everything changes, including myself. Sometimes it's enough to make me wonder why we even have a dyno forum and waste our time bickering about these things I listed it as 1.0CF because that's what it is. Some shops run 1.2CF and don't say so...that is even more silly IMHO but they sure thump their chests with the numbers they produce!

 

You seem to be struggling here so let me help you out.....

Use Shoot44 Mode on dyno dynamics, that locks the major parameters down including CF and ramp rate (ramp rate ensures each car gets the same loading and makes spool comparable).

Time of year makes no difference, the DD dyno uses weather parameters, Barametric Pressure, Air temp (AT) and Intake Temp (IT) and applies its own correction factors so that your car should produce the same numbers whatever the weather conditions


But thats exactly the point, Shoot44 is there to lock things down and make the "same dyno" comparable between shops and stops all this nonsense of adjusting CF

 

Very nice! I may consider the BBX since full kits can get pretty pricey.
