S52 dyno results - low?

[matt]

So... we should benchmark NA motors against turbos?

why not? we're talking about similar cost here.

Performance per dollar you can't beat a turbo setup.

Turbo an s52, then compare. ;)

at what cost? :p

[Van Westervelt]

couple sets of my wheels. lol

Um, I think the 0 280 150 917 is a 19 lb injector. The blue top 0 280 150 947 are the 24 lb injectors.

You are correct, I have some mystery injectors. The only documentation I found on these was that they flow 200cc/hr, which is ~ 19 lbs/hr.

There seem to be 2 BOSCH PN's for the 24 lb/hr rated injectors:
0280150947
0280155917

The second seems to be the more prevalent one mentioned here, which is the Gen III 24lb design from Bosch. I'll be on the hunt for a set of those.

Now, the real question is: how did this result in my running *rich* above 6k RPMs?

any idea what the PN on your injectors are?

Agreed. At 10 PSI you see the S50/S52 engines in the low to mid 300's.

Not a bad number for 10 psi on an M20 - but it can hardly be described as *bone stock*

Yes, they are the 0 280 150 917 PN that FredK and I mentioned. Not sure how I connected with these, it was over a year ago when I started sourcing parts for me swap.

0 280 155 715
These are the slimmer updated plastic housing ones that turner sells. I have a set in my s50 right now.

You guys are trolling the wrong section for M20 turbos...

yeah, those are 19# (18.25 technically)

the injectors are probably not the cause of your rich condition.

nah, I just like antagonizing you guys. it's pretty easy actually.

never heard of one breaking actually. the front diff doesn't like repeated hard launches though (ie drag racing). :p
