almost 0 loss at 5300ft? wow, that's impressive. What about spool up? Evos and STIs loose an average of 500rpm to get full boost. Mine went from 2500rpm (sea level) to 3000rpm (6500 ft.), and adjusting the MBC did not help at all to fix the issue.

I'm pretty curious to see how 335s do at the quarter mile track over there.

Also, your Procede 335 is pushing more than 360 horses at the cranck...more likely 390/400. (330 whp average with an aproximate 20% drivetrain loss)

BTW, FI cars loose more than 2-3% at 6000ft. I lived 2 years in Colorado Springs (6500 ft) and my Evo was almost a full second slower in the quarter mile compared to sea level. My estimate is a 18-20% loss. There's also the spool up issue: max boost at sea level was around 2600rpm...at 6500 it was achieved at 3100rpm (got lag?).

My car dynoed 310 whp. Most proceed cars on 91 are dynoing 315-320, mine was slightly less due to the dyno being at 5200 feet in boulder, co.

Also, BMW has already stated the drivetrain loss for the AT is 15% and the MT is 13%. This is generally accepted on this forum.

My 2-3% estimation was based on the elevation of 4500 ft. in which I raced the srt8 jeep, like I said before.

The only people with 330whp are either 93 octane or 91 octane with catback exhaust.

like corn just said, the loss was very small. enough that shiv didnt use the typical altitude conversion factor on the dyno to compensate. when he did that, the numbers were obviously inflated, like 300whp stock if i remember right.

and you would have to ask shiv the spoolup question, im a turbo noob

Hey man, were you the one in the black E90? Those whp numbers sound miiiiighty familiar.

I've heard several stories of SRT8s holding 2-3 car leads through the quarter on stock 335s. How quick have stock 335s run? Grand SRT8s have ran as quick as 12.8s with quite a few posting 13.0s. Regardless, both vehicles are very impressive.

If anyone in Reno would like to have a friendly race or two with a stock SRT8 I'm game. You should have the edge given our elevation.

Stock 335s run 13.3-13.5. Procede 335s run 12.9-13.0. That's why I said that something wasn't right on this video from Kuwait where a stock 335 kills a Grand SRT8. In countries like Kuwait the average temperature is 120-130 degreees. Therefore FI cars loose more power than NA cars over there. (I lived over there for one year)

The SRT8 is faster in the 0-60 and in the 1/4. As you may have noticed, the 335 i is faster on e90post.com than it is in real life.

Let's just say that I started behind the Jeep and by the time I hit 100 I was ahead by 6 or 7 car lengths. I must say though, it's amazing how fast those things are considering it's weight. I imagine it's gotta weigh at least 5500 lbs.

While I agree that an Chrysler SRT-8 vs. a stock 335i would be close, the funny thing is that you'd never know if the next 335i you challenge will be PROcede-equipped or not.

Only when you get walked away by a 335i will you know! And, please don't say that this will never happen, b/c I know from first-hand experience that it absolutely can time and time again (as a guy in a brand new 300C SRT-8 tried over and over again for ~ 15 min. to just keep up with me and he could not...and believe me, he was trying ). I think he was totally stumped and pissed that he could not beat a little Bimmer 3-series...he wouldn't even give me a respectful thumbsup when we both exited the hwy. at the same exit.

While I agree your car is crazy fast, I think its weight and its less than ideal aerodynamics hamper its abilities at higher speeds.

It's hard to say exactly how many car lengths. But if you calculate the loss in power at 4000 ft. I put down about 365 crank hp at 5k feet.

Just look at the power to weight ratio.

335i/Procede=9.79 lbs per 1 hp.

Jeep srt8@4000 (estimate just 8% loss)=391 hp and 4800 lbs=12.27 lbs per 1hp

Whadaya think would happen? It's not like my car shifts slower or something

It wasn't even close.

FWIW, I've beat my buddies 300c srt8 at 4k feet, every time, by a significant margin, I think they weight about 4150lbs.

Once again, look at the 300c srt8's power/weight @8% loss due to altitude.

10.61 lbs per 1 hp.


These number's I've mentioned doesn't take into account that I put down about 420 lb ft torque at the crank.

If you looked at the torque/weight ratio, I would be way, way ahead.

There have been many tests at higher elevations on na vs fi. Just do a google search. I've seen two tests comparing sea level to 6k feet with the na cars losing 14-20% of their sea level dyno power at 6k feet in colorado. Whereas the FI cars lose 2-4%.

Now a good race would be at procede 335i vs 300c srt8 at sea level.

Now a good race would be at procede 335i vs 300c srt8 at sea level.

A normally aspirated car does not lose 8% of its power at 5,000 feet! At 4,500 feet the air pressure is 12.5 PSI versus 14.7 PSI at sea level. 12.5/14.7 = -14.96%. So at 5,000 feet the car is losing over 15% of its power. There is no way for a normally aspirated engine to get this power back. 15% less air pressure equals 15% less power. The 335i turbos add additional boost to compensate, hence the very little power loss at altitude for a turbo car such as the 335i (not all turbo cars compensate as well).

Notice your on the wrong thread then, my first post says "my car is proceded FYI". I won't comment on what would happen if I was stock, because that's not how I've run the jeep or the 300c srt8's.

What sort of times are proceeded 335s laying down? 13.0s? 12.9s? If thats all thats done to it I highly doubt it would walk away over a 1/4 mile from even a stock GC SRT8. Win maybe but not walk away. A modded GC SRT8? Headers/Catback/CAI is a 12.5 capable setup on our rigs.

It's quite obvious that you LOVE your big Chrysler "gangsta-mobile" POS, but please, don't even begin to tell me b.s about my particular run in with your exact make and model car. I guess you don't know that a PROcede-equipped 335i has close to 400HP and more TQ than the 300C SRT-8, and the 335i weighs 560+lbs. less than your POS BOAT!!!! My car (when I had the XEDE; the PROcede is supposed to add a little more HP/TQ) dyno'd at 322WHP (~ 379BHP vs. 425BHP) and 378 lb.-ft. RWTQ (~ 445 lb.-ft. TQ vs. 420 lb.-ft. TQ), and more significantly, weighs A LOT less. So, what do you think is going to happen? Duh...

These posts were from another thread on here when I chimed in (on my SRT-8 run in) on that thread...

"Speaking of a rolling start, let's just say that a Chrysler 300C SRT8 totally got walked today by an XEDE-equipped 335i! :rocks: The SRT8 guy didn't exactly look happy, after his 425HP/420 lb.-ft. TQ 6.1L Hemi V8 couldn't keep up with the little BMW 335i...he probably doesn't know the 335i is a FI twin turbo and he certainly didn't know that this little Bimmer has a little "something extra" under the hood. I thought those Hemi V8's (especially the SRT8) have a super powerful top end????

Nonetheless, it was funny to see how baffled and frustrated the SRT8 driver looked! He didn't even give a courtesy thumbsup when he exited...sore loser, I guess!"

"I understand your point about going to the track (not the "from a roll" thing), but FWIW -- the SRT8 guy didn't get caught off guard for the 20 min. "on/off" exercise of "spirited driving" today. I was just under the impression that the 300C SRT8 was crazy-nuts fast...and it is, but apparently, the XEDE-equipped (and PROcede-equipped) 335i is much faster; in fact, I actually think a stock 335i could hang in there or be slightly ahead of this car as well. I also think that many, if not most Chrysler 300C SRT8 drivers think they're hot sh!t; it's just good to know that they too can be knocked off their high horse by a few select cars, including the 335i, without too much effort."

I admitted that the SRT-8 is "crazy fast", but sorry, dude, there ARE faster cars than your fugly gangsta tank with the wannabe Bently grill!
