More than likely the injectors going 100% may have caused some issues. Overall it looks like pretty decent results, probably 550 crank HP or so based on their dyno reading similar to Buschur/STM's Mustang which is good for 124 mph traps. It also makes sense that the 1000cc injectors are maxxed at that power level assuming that E85 takes ~35% more fueling. I like how the boost is holding a solid 28 psi right to 8000, my GT30 setup does well until 7200 or so then fades quickly to 24 psi by 8000 which can be annoying.

My car is likely about the same power level using 93 octane but has a tubular manifold, test pipe, and intake manifold instead of the higher boost/E85 combo. I'm going to go out on a limb here and say there is potential to reach 500 whp on that dyno by swapping in the mods I have (Tubular Manifold, TP, Intake Manifold) PLUS cams running E85 on the BB-X which is probably a good 650 crank HP. It definitely would need AT LEAST 1200cc injectors to support that on E85, probably 1400-1600cc would be a better bet to avoid 100% duty cycles though.

So from my perspective I approve of this turbo!

I'll definitely consider upgrading to these internals or GT35 sized wheels when I grow tired of the GT30 limitations.

 

^Yes, it appears that replacing the HFC with a test pipe and the addition of camshafts and adequate fuel supply I would assume this turbo could approach 500whp on that dyno. That would be a serious street setup that spools incredibly fast and enough power on tap to satisfy an insatiable appetite for power. Good work GST and CBRD. I'm looking for more great results from this turbo.

 

Not to make any excuses, as this turbo really doesn't need any from what I have seen so far, but please remember what I stated in the first post that this Evo 10 has been sort of a "runt" compared to other 10's we have had through the shop.

Other E85 Evo 10's with the same type of mods are making 340-360whp on stock turbo.

However, what to look at here are the gains between the two turbos on the same Evo 10.

Yes, upgrading the cams will make more power, as can be seen here: https://www.evolutionm.net/forums/ev...ford-cams.html

Adding a test pipe will also produce more power, espically at this level of boost.

I feel this Evo 10 is a good example of a "middle of the road" build that most people like to see as real-world results.

A tubular manifold will add lag, but with some top-end gains.

I'm sure there will be more BB-X examples coming very soon.

Thanks for posting this... I wish we could get info on the BBX for cars running regular pump gas. I have yet to see an E85 station anywhere around me... ever...

Anyway, do you have another customer lined up for an install with pump gas?

 

Bryan, do you know how your dyno compares to ATP's? Here's a dyno of the GT3076 on E85. The cars seem to be similarly modded.

 

Based on those trap speeds it looks very similar power wise, probably closest to a typical 20% losses DynoJet based on the trap speeds. The difference being that if the BB-X can hold boost better above 7200 rpm it should have the edge once the mods start piling on and you are running higher boost levels. With the 1000cc injectors I bet they also were at 100% duty cycle and capped at similar power levels on E85.

 

Good point rogue. There is much talk of water injection, high octane fuels and corn but no mention of 93 octane pump gas. The masses are not running around on water injection, high octane fuels or E85. There is one ethanol pump in my area however, it is 35 miles away - not feasible.

 

Dude your a moderator now.. jeez where the hell I been.

Well I figure, if anyone brings out a turbo bring out specs on what will attract the masses as a whole. I still see E85 as far and few between due to accessibility, but it is good to show high horsepower numbers. I guess we have waited this long for something, no harm in waiting for pump gas specs.

 

I bet this turbo will max out the IDC on the DW 800cc injectors on pump 93...

 

My BB-X was spooling almost like stock @ sea level. I'll see if I can dig up some data logs, but I was seeing full boost in 4th at 3400 rpm when all was said and done.

 

Yeah I can get the stocker to spool about 2900-3100 in 4th to 25/26 PSI, so it does not seems like too bad of a compromise.

Were you running 800cc or 1000cc inj.? What were your IDC's like?

 

1000 cc... I saw 76-78% IDC at 30 psi at 7500 rpm at approx 12.0 AFR via the injectors, but actual 11.6 AFR w/ methanol injection.

 

So I would assume the IDC on 800cc would be close to 100% at that rpm and boost level.

 

Definitely, this was with AMS' inline pump too which richened up my AFR's approx 0.5. My particular set of injectors were rated at ~ 1010 cc/min.

Good to see some Mustang dyno numbers on my turbo... mine was certainly making some serious torque before I threw a split rod thru the side of my block

 

I'm sure you could up the base/idle pressure a bit to get a bit more flow out of the injectors if you had a adjustable FPR along with a higher output pump.
