Went back to the dyno today....
Well - some of you were right, no 600 at the wheels. :cool:
However, there is more power and MUCH more torque, and a MUCH improved curve. John at Vitesse has the files, and TurboX (IAN) has the video. Both will soon be posted, I am sure. This will be the end of my 951 tuning for a time. I am going to concentrate on my 3.5 single cam BMW turbo that I am building for Bonneville. It will be over 900 HP/TQ at the wheels and be geared for 240++ MPH. No, I would never sell my 951, and I will be at the fest next year if it kills me. |
what chassis will the bmw engine be in?
|
Sweet!!
And oh, why single cam for the BMW? Since BMW engines are pretty cheap and the 4 v heads flow enough for 1000+ hp without touching? |
There is an aritcle in last month's turbo magazine documenting a '91-'93 turboed M5 motor swapped into an E30 chassis. At on;y 24psi, it's pushing 875RWHP. Good luck with your's it seems those motors really respond nicely to Forced induction!

M30B35, but why. While a cheap engine you'd be better off starting out with an early M50, non vanos. Cast crank, forged rods stock, and a significantly superior head. The M30 top end is a bit suspect and the exhaust ports are a joke. Oddly enough I have an M30B35, an S38B36, and an M20B25 all on stands in the garage.
Highboost, while the castings of the blocks are similar between the M30 and S38 the engines are significantly different. It's much easier (although more expensive) to make power on the iron block M5 engine. |
The good old 3.8l M5 iron block engine is probably the best start for an 1000 hp engine short of big block V8's.
New rods and pistons and you're good to go :bowdown: No ST, how about some more info about the 951! |

Here are the charts. 543/571 HP/TQ at the wheels.
I have the ZT2 trace from this run, if anyone wants it. There is no MAF trace on it, so please don't ask. |
Ecellent, congratulations. Especially remarkable is the low rpm level at which you reached max power. What boost and fuel did you use for the pull? Still stock block?
|
What boost level were you running? I hope you aren't disappointed ST as those are still great numbers! The thing that stands out the most to me is that awesome low-end. ~300rwhp @ 4k and ~400rwtq @ 4k, then a ~200rwhp and ~170rwtq jump 500rpm later.

You got 2k rpm's of good power. Thats better than most cars that have large peak #s.
props and don't be disapointed. 540 is nothing to sneeze at. |
Not bad,not bad at all...!

what was changed from the previous run of 533?
what did you expect to get? what are the potential reasons you came up short? excellent numbers! |
Why the drop in Hp as the RPM's increase? Big valve head and cam should have kept pulling?
|
I am truly disapointed, don't you dare call me again tool, that was totally lame 570rwtq dude, my diesel winebago has more torque than that. We are done as friends, I am sending a full apology to Tony my master and mentor. :mad:
Tool, you have been added to my ignore list. Good bye Okay, I am messing around "good numbers" ! |
