M50 Dyno Chart! I guess it's time to go turbo...

[WADE30]

Well I really should have listened to you guys. I thought I felt 200whp+ but needless to say I fell short. Time to start sourcing turbo parts!

Performance Specs:
Full OEM rebuilt M50tu
TRM Custom Tune Chip
S50 Cams
24# Bosch Injectors
3.5" Euro HFM
Amsoil Intake
Super Sprint replica headers
Custom 3" exhaust, no Cat, Vibrant 3" Muffler
ZF Transmission
3.25 LSD



Thanks for looking guys! I plan to make a new intake boot for better flow, and make an intake heat shield. The heat here really soaks these filters bad. I have a friend here who bought light-weight pulleys, he dynoed before and after, showing a gain of 12whp. Worth it for $200-250?

Looks like some good numbers there, pretty nice! How loud is that 3'' exhaust? Do you have any vids of it online somewhere?

12?? I find that hard to believe, but I sure as hell hope you're right..

Ok I beg your pardon. Wrong Amount but decent amount of WHP none-the-less.

Man out of all the cars I have ever owned, this exhaust setup sounds the coolest/best. Not raspy or drony. It is great deep rumble and screams up top. And not too loud at all.

I will try to record a video this weekend and post it up. Drive by and idle/rev.;)

Good numbers for a m50 dude! I made like 170whp on a stock motor with a chip and shitty exhaust...

Turbo is by far the best gain for the money.

Don't lose sight of the big picture in the peak number... Your curves look perfect, your AFRs are great...

My car made 186whp with basically the same mods (stock MAF and green injectors) and it was tuned on the dyno.

Quick question...Can having bad u-joints on a driveshaft develop a higher drivetrain percentage loss?

What kinda dyno were you on Matt?

Not awhole lot but yeah it can take away alittle.

Thanks Matt that's encouraging.

is 197 really not enough fun? seems like going turbo would make the motor swap less worthwhile or cost effective. I think a reliable 197 would be pretty fun to not have to worry about things.

I'm thinking about trading my gt3582r for a m50 swap. I know it'd be a hell of a lot better than the stock auto eta i have in it now, but is it really worth getting rid of the $1,300 turbo for?

I mean 175ish hp isn't really all that impressive.... but i guess it could feel pretty good in an e30.

[WADE30]

I am just whining to be honest. The car is quick and loads of fun! And due to power/weight ratio it quicker than a lot of other cars on the road. It is reliable and I average 27MPG. I don't plan to turbo for a while. Trust me I love the car :D

You're making good power!!! think about it like this, you're making about what a stock S50 would make which isn't bad at all from a 2.5 liter. Another 50 HP from bolt ons? can't complain about that.
