Hey guys, nice to meet a couple of you! It was a good time, 6 or 7 cars showed up... 5 Dynoed a couple watched!

Here are the results, and Mods per car in order of Dyno Pulls:

2009 Black BMW 335i Sedan 6MT STOCK 6,000 miles
Made 258 RWHP & 284 RWTQ on 91 Octane Pump Gas

2007 White BMW 335i Coupe 6MT Mods: JB3+, Frt Mount Intercooler, and some other mods, however his diverter valves were literally 'ZIP TIED' on to hold boost, as his aftermarket ones were not done yet.
Made 315 RWHP & 342 RWTQ on 91 Octane Pump gas

2008 White BMW M3 Sedan 6MT Mods: Crank Pulley, Offroad Front Pipes, K&N & RPI Scoops
Made 347 RWHP & 253 RWTQ on 91 Octane Pump gas
Made 342 RWHP & 260 RWTQ on 100 Octane Race Fuel

1998 Silver Pontiac Trans Am 6MT Mods: Headers, Exhaust, Suspension (the works!)
Made 322 RWHP & 327 RWTQ on 91 Octane Pump gas

2008 Grey BMW 335i Sedan Auto Mods: K&N Drop In
Made 268 RWHP & 291 RWTQ on 91 Octane Pump gas

2009 Black BMW 135i Coupe 6MT Mods: JB3, CP-E DP's, BMS o2 sim, golf-tee
Made 328 RWHP & 366 RWTQ on 91 Octane mixed w/ a couple gallons 100 Octane Race Gas

Thanks to all that showed up! Special thanks to Xtreme Motorsports, they provided Water, Donuts, and some movies for Kids to watch! It was a good time!

Let me know if any of you would like to put together another one... as long as we get 7 cars... they said they'll do this on Saturdays (obviously more exciting, when it cools down!)

Peace,
Dave

Thanks for setting it up, Dave. The temptation to mod is now greater than ever.

Your car is RIPE for it! Nice looking Ride & Family Lee! Let me know when you want to go back!

Peace,
Dave

[sbdavis1]

Thanks again Dave. It was good meeting you guys. I'm updating my JB3 asap and putting the DP's on! Once it cools down a bit we should try it again.

maybe next time i'll throw the 100octane in and actually see some gains! LOL.

[FikseGTS]

what kind of dyno was this one? wow, the M3 is so weak in the torque.... they should have used the v8tt that's in the new 750i's in the M3.....

[SCCAForums.com]

You too Spence... ya you need the 100 Octane... let's do it again when it cools down some... although they did a nice job keeping it as cool as we could probably expect!

Fikse... Dyno was a DynoJet, and yeah... M3 doesn't have torque... but that's why it has 8,300 RPM's! And to be honest... the 'tq' in the M3 feels MUCH better than the TQ from my previous M5!

PS... if they do the V8TT in this M3... SIGN ME UP!

[DLSJ5]

Thanks for posting! Great to see some #'s on independent dyno's. I see that the 100 octane did nothing on the M3, that's what I found too.

[stimpy]

Sounds like you guys had fun!

I'll be bringing a fully modified 335i (JB3, Helix IC, AR DP, etc) when it cools down

Can you only get 91oct in the Phoenix area?

The gas stations in AZ carry 87, 89 and 91. No 93 here. We do have a couple places that carry race fuel (100+).

[shyestsparks]

What was the outside temp when those dynos were run?

[shift330]

You guys are dyno'ing your cars in this 115+ degree heat?? It's 1am here right now and still in the mid-90's were you guys inside?

[Sniz]

you boys out there are ripe for Meth injection, you'll see big gains w that heat.

[SCCAForums.com]

Yes, it was about 110 Degrees... they had huge swamp coolers, keeping inside temps to low 90's... but Humidity was also ugly that morning, combined with Swamp Coolers, giving 35% Humidity.

Obviously the Dyno's weather station attempts to correct... but there's only so much they can do.

It was still a great time... and lets everyone know what our cars are making during our 'cool summers' here in AZ!

LOL, we drive them in this heat, so why not dyno them? As Sniz said, good baseline to compare if you ever decide to try meth/water injection or to see the impact of high temps on power output.

The auto manufacturers have testing facilities out here for a reason...

the #s overall seemed a bit low (maybe the heat and 91 oct gas? or low reading dyno?). the M3 did well, but guess race gas does nothing at all for them. i forgot who but someone posted on another thread insisting that race gas does wonders for M3 too .. hmm

On an N/A car race gas only helps if the compression is high enough to utilize it. Most cars are built to run 100% on 91-93 octane gas. I think 93 octane will suffice for up to 10.5:1 compression or something like that. Seems like I remember reading that 100 octane is for 11:1 and you can get (leaded) up around 115 octane for 12:1 compression ratios.

This shows a few different fuels (octane ratings, oxygen enriched, etc.) and the compression ratio's they support or recommend.

On a turbo car timing advances and boost levels create a totally different ball-game with regards to octane. But on N/A, it really comes down to CR (compression ratio) although with a tune you can advance a little timing and maybe gain a little power with higher octane, sometimes.

FML. The cars run so much nicer on 93.

[shift330]

At least y'all had fun, even if it was balls hot. I was stuck in a court room in Bisbee all morning with just a ceiling fan

ouch. not a sigle part of that sounds fun....

the numbers were a little dissapointing but it at least gives us an idea of what we're running for a good part of the year. the conditions inside the shop were fairly similar to a typical summer night..a little cooler actually. lol.

i wish we had 93 out here...the best we can do is throw in some 100 from a few stations around the valley and get a mix somewhere above the unfortunate 91 octane.

but when a lot of you have your cars garaged because of the snow...we'll be enjoying our 65 degree sunshine.

+1 sign me up. dp's go on soon and I see meth in the near future.
