Powerband is a little bogus but since it was the 1st dyno tune we didnt wanna push it. Powerband dropoff can be fixed with some cam adjustments. Mixture and timing were conservative for reliability so a little more can be squeezed out but Im happy.

your dyno is the size of postage stamp LOL

All that time effort and money, and you put a dc sports crappy strut bar on it...lol

Good numbers, just need to clean a few things up in the bay.

LocoJoe

LOL yea I just had that bar lying around I really need to give it some love. Engine is happy so now love to the rest.

MoreCowbell

Very nice! I think you can post some more chit chat up now

Looks good to me !

LocoJoe, which Darton sleeves do you have in this ? MID's ?

LocoJoe

Yes sir. Bored to 85mm

Thanks

very nice man we made pretty much the same power out of our little motors man. b16's getting it done

LocoJoe

Yea this is the last dyno sheet after problems were fixed.

sanman000719

very nice what problems did you run into man

i had some as well fuel pressure and voltage are falling off up top on me but my a1000 is probly taking a **** on me lol

LocoJoe

I had problems with the intercooler and my compressor housing let go of the bolts so..... We fixed that and got to the results above. Cant ask more for a B16 with stock fuel lines and a little walbro255 with ID1000s.

sanman000719

true only differance i see between us is fuel

what duty are you seeing with them id's, and base pressure

i was at 89% at a base of 70psi on my little 1000's

i love it when people say you need 2200's to make the descent power lol

sanman000719

well just found my issue lol 9v at the pump, and 7v at higher rpm damm street VR is toast oh well

love to see nice b16 builds man, and you have one keep up the work and squeeez the power out

B20luda

surprized it didnt make more power, i think that .63 hotside is killing power... those cams are pretty big for that small of a hotside imo

Actually its not "killing power", even with those cams, as he still qualifies the use of those camshafts by being over 61lbs/min + to begin with. Remember what the purpose of this car is. His car was made for extremely street oriented with occasional strip use. The purpose (and reason) why we stayed with the 71mm was because of the fact that the B16's inherent lack of torque was made up for from the 4000rpm-8200rpm powerband. Sticking a .82A/R on there would have done little difference except for perhaps at most 30-40whp at the last 600-700rpms of an 8500rpm powerband; an area that really doesn't help him for his trap speeds at all at this point; and on top of that, less powerband available for the street use.

If he really was looking for more than 100whp or more, it would make more sense to use a larger exhaust wheel such as the 74mm in .63A/R than to just simply putting a larger housing on the same size wheel. Yes, some have argued that "spool" characteristics may change by as little as 300rpms, but still doesn't address that the larger wheel would be more beneficial than a larger housing (all other things being equal).

LocoJoe doesn't ever plan to be at a peaky 600whp. He'd rather be at over 500whp for 99% of the powerband, hence his reasoning for staying with the smaller 71mm exhaust wheel and .63A/R housing for his purpose of the B16. Remember, he originally wanted only 550whp PEAK, so, I'm sure he's happy. He not afraid to push boost, which is nice to have for a change instead of these 10psi at 500whp peak with no powerband at all with 80lbs/min with a 6765 or similar setup.

This was as good as an in-between as one could ask for for the build.

All I ask left is that a filter of some kind be put onto the turbocharger.... When they're naked open like that, God only knows what could happen

LocoJoe

Dont worry, Its got a Turbonetics mesh in there since an air filter cannot be fit due to the clutch slave.

TheShodan

iTrader: (14)

Using a Prelude 4th Gen clutch slave will help with that. but "Mesh" isn't enough.

LocoJoe

I will definitely look into that tommorow.

great build...

i have a few b16 long blocks i have laying around... now i might want to build one just for fun.

Nice...
Q: when do you get full boost?

m3tech95

Nice build....

YC Underground

Nice build with good numbers, congrats
