How much hp have you gained?

[PhillyCheese]

I thought this would be interesting:

What year and model BMW do you have?
How much hp have you gained due to mods?
What mods (if you want)?

[CMT]

It should be interesting to see just how many/few people haave actually done a baseline dyno, and then returned to that same dyno once modded. And even then the differing weather conditions make any real specific comparison useless - but it does make for a good ballpark.

My car with intake, exhaust, ERT UDP and Dinan Stage II SW made 225 hp / 225 tq.

Later with the same mods, it made 215 hp / 217 tq with a slipping clutch and trashed guibo.

And later, with the same mods minus the ER UDP and AA LTW fly and clutch added it made 217 hp / 221 tq. I also had the 3.46, but a diff does not show its acceleration difference on the dyno.

All on the same dynojet, on different days and conditions.

I have a 2002 330i. With only AA exhaust, I had 182.8hp to the wheels (temperature was about 65 degrees). With ECIS intake, RE pullies, AA chip and the same exhaust, I put out 187.7hp to the wheels. Both dynos were at Eurospeed Performance with their Dynapack.

So, I gained less than 5 hp to the wheels, but on the second dyno, the temperature was about 95 degrees. Thirty degrees makes a huge difference.

98 m3 aa stage 1 im hoping to gain at least an extra 140 crank

From Heads, Cam, Exhaust, Under Drive Crank Pully, and POrted TB I went from 313RWHP to a little over 400. And from 328Ft Lbs of Torque to 384 Torque.

In the fall it will be time to spray it. A 75 wet shot will give me 70-80RWHP and about 130Lbs of Torque

500Ft Lbs of TORQUE. MMMMM Yummy.

Nitrous = Torque in a bottle.

Stock my car made 208 rwhp 209 rwtq,

Dinan intake and UUC Exhaust it made 215 rwhp 217 rwtq

Dinan Intake, UUC Exhaust, ASC delete, ERT UDP it made 225 rwhp 226 rwtq.

All on a Dyno jet and SAE corrected.

[Duckydos]

Butt dyno tells me 100hp to the wheels :\
/has nothing to add to thread.

US 2.3l E30 M3
Stock 149rwhp 135rwtq

Cams, MAF, Chip, resonator, exhaust....200rwhp/165rwtq

Can some 1 tell me around what I should have with my mods.No dyno yet.

97 m3. new clutch
uuc udp,540 hfm, 3.5 aa intake
s50 manifold aa exhaust
uuc flywheel,turner chip uped fuel pressure reg.

Future plans shrick cams and headers and custom tuning for it.

First a couple of questions, what software do you have? Currently Dinan is the only company making a program to run the euro HFM on OBDII cars.

If you actually do have this its probably 235 or so rwhp.

I have the shark injecter.we also uped the pressure regulater and my shop did some other stuff also.Its there right now getting a few little things fixed.

When I was at turner they told me that there are working on a cat system.I want to do theres cuz a few said they lost low end with the track pipes

chipped 1.8T =

[TINIK]

I don't have original DYNO for my M3 motor

but I only have Dinan chip, Remus muffler, fan delete for mods.

223 whp, and 217 whtq proven on a dynojet (50ft above sea level, in 85*F 95% of humidity)
