E30 S50 Dyno..

[CincinnatiKid]

Damn, I made 260/244 rwhp/tq out of my s50 with basic bolt ons.

What're your basic bolt ons??

[White325is]

Headers, exhaust, chip and intake.
That be all. This was my second dyno I was on.
Numbers from both was very close, by like 5/10hp
This was the only one I had a video of.

im not thoroughly wise on //M motors but I saw a Z3 M coupe put down 225whp on a dyno at Grossman in Louisville 2 years ago. everything was completely stock with 60k+ miles on it. Seems slightly low to me... Regardless, thats a pretty Alpine.

those are numbers that a fairly built s50 would put out.

I will say.. This car is FAST;)

Sohc- wanna send me that pic in your sig? (In full size?) that picture looks sick.

I can't wait to see this car in person sometime, looks awesome.

That motor is one of a kind.

I have Dinan software, headers, exhaust, and a cone filter. I put down 232whp and 207ftlb 3 different times.

Well, I can tell you I didnt build the engine. The PO didnt know of any mods done inside either. So I dunno..
I just know what the dyno tells me.

Dyno numbers are completely useless without another similar motor on the same dyno to compare against. You have no idea how that dyno is calibrated so the numbers are meaningless, just make sure your A/F is good.

My s50 with 3.5inch hfm, ebay headers, PS delete, AC delete, tune, stock injectors (maybe forgetting something, it has all the boltons besides cams) put down 225rwhp. The dyno shop said that stock s50's consistently put down 200-205rwhp, and an m54 with some minor stuff down put down around 215-220 right before I went on.

Point is, you need a car to compare to, you can't just say the number seems low.

Completely agree. OP, if the car pulls strong that's all that counts. Comparing dyno numbers with sooo many different variables is like measuring epenis sizes. I can have a friends dyno tell me I'm putting out 300rwhp on a dynodynamics dyno. My ewang is f'n huuuge.

Did he get out of the car while it was still rolling?

I bet it is fast just by seeing the torque of it on the rollers.

I put down 247/242 rwhp/tq a while back, raceland euro SS -> dual 2.5" -> UUC System U, S52 w/ obd1 mani, 3.5" hfm, and a trm chip. Same day, same dyno, 1 hour earlier an e46 M3 put down 258whp stock.

If the dyno is reading low, I wouldn't be worried, but at face value I'd check the tune, and maybe see about the fuel filter / fuel pump.

Would there be a big difference between OBD1 converted s52 w/ 3.5 HFM/24# injectors/Dinan and this? Cause mine threw down about 240 at the wheels, and I'd concur this seems maybe a hair low. Could be environmentals certainly
