So this is the same car that ran 11.82 at 117.91 mph.
I wanted to see what the car would run on stock boost to get an idea if the baseline results make sense. The car has 17" Kosei wheels/Hoosier DRs, rear seat delete. Engine is totally stock (JB3 in Valet/Bypass mode). 91 octane Shell. My runs were very consistant. I consistantly couldn't get into the 12's LOL. I was hoping to get into the 12's with the Hoosiers. With better traction conditions, 12's are possible. And I would be willing to bet some of those 13.0s are actually 12.9x runs. Best 0-60 runs were 4.5 seconds.

It is very interesting to watch the boost gauge. It is amazing what low boost levels the stock tune run. Usually only running in the 5-7 psi range the majority of the time. And if you look at 0-60 video (the top of 2nd gear) you realize stock, this car is still pretty damn quick! I also screwed up a run or two with wheel spin. So yes, even with Hoosiers, the stock engine/boost will spin and screw up your runs if your not careful. And the Hoosiers were set at 24psi.

Here are the half dozen runs:

JB3 1.3 Map #0 (stk boost)
50F, 91 octane. 17” Kosei/Hoosiers

Run#1 DS Mode:
¼ mile: 13.0 sec at 108 mph
60ft: 2.0 sec
1/8 mile: 8.4 sec at 86.2 mph
0-60mph: 4.6 sec

Run#2 DS Mode:
¼ mile: 13.0 sec at 108.5 mph
60ft: 2.0 sec
1/8 mile: 8.4 sec at 86.9 mph
0-60 mph: 4.5 sec

Run#3 DS Mode:
¼ mile: 13.2 sec at 108.2 mph
2.1 sec 60ft
1/8 mile: 8.6 sec at 86.4 mph
0-60mph: 4.7 sec

Run#4 DS Mode:
¼ mile: 13.0 sec at 108.5 mph
2.0 sec 60ft
1/8 mile: 8.4 sec at 86.9 mph
0-60mph: 4.5 sec

Run#5 DS Mode:
¼ mile: 13.2 sec at 108.2mph
2.1 sec 60ft
1/8 mile: 8.6 sec at 86.4 mph
0-60 mph: 4.7 sec

Run#6 DS Mode:
¼ mile: 13.0 sec at 108.7 mph
2.0 sec 60ft
1/8 mile: 8.4 sec at 86.8 mph
0-60mph: 4.5 sec

How would this compare to the track? Take away .6 to 1.1 mph depending which drag strip you visit. (Vbox Correction) So probably 107.5-108mph. The wheels/tires are about 76lbs lighter than stock RFTs (rotational weight), with a better launch, so there is another 1mph. And then another .60mph probably with the weight savings. So if this was totally stock with Runflats, that would put this run at 105.9-106.4mph. Right where it should be totally stock.

But now back to the JB3/Stock Comparison. In the same exact configuration the other week except with 100 octane, the car ran 118.2 mph. So almost 10mph faster. That is almost 100hp increase. If stock is about 279 hp, I would say my car makes around 370hp. Which is exactly what Terry had figured a while back. What amazes me is those cars with the amazing 400+ whp dyno resuts! I figure they should be running 121 mph or so when they hit the track?

Those are still some good times for stock and I think most would not even see those numbers...You have mad skillz when it comes to the drag strip thats for sure!!

I'd like to see some mods on your car jus to see if it makes that much of a difference.

[hotrod182]

Im really interested in trying out the Riss Racing scoops to see if there are differences. With this kind of real world testing, you can make 3 runs, modify something, make 3 more runs and you WILL see any performance increases.

I have always believed that cooler air intake will always be a benefit.

I was looking at the new V8 twin turbo the other day. Kind of amazing what intercooler setup they have. I noticed they have a seperate liquid intercooler tank. You could probably run ice water in there for some 1/4 mile runs! They look pretty small. I wonder if something like this can be adapted to our cars? However, having the hot radiator air blowing on them makes that location seem less than ideal.

Have to agree with Hotrod......when I drive my car in stock mode or borrow my friends stock 135, I am still very impressed with how fast stock is.

I think even at 12-13 psi things are faster, but still pretty tame.

It's not until my boost gauge starts seeing 14-15 psi that I start to grin...lol.

1st gear is pretty quick, but kind of lags from there on. Doesn't have the explosiveness of running higher boost, but still pretty impressive numbers nonetheless.

[Sniz]

hmmmm how is your car trapping that high on stock boost? Aren't most 335's hitting 105 or so on stock boost?

I think your cars run so damned fast because you are either at 0 throttle or 100% throttle.....it learns to be a beast!

hell I barely got over 108mph on V1.47.......and that was on a good run!

[Septro]

yea those are some crazy stock ETs and Traps.. Grats tho but I'd like to see more ppl get close to that

[Xander]

You make a very good point about what kinda numbers the 400 whp cars should be putting up at the end of the 1320.

X....

[hotrod182]

I would think 120mph+ with that kind of HP. Terry has done it in his 135i and the JB3 cust who had the mildly modified 135i which shouldnt dyno that high did 119.7mph?

Most people are not as repeatable as you for launching and shifting. That is why the B5 S4 crowd started doing FATS tests. It is good measure of the vehicle running through the rev band in a single gear and illustrating power differences and not the individual driving (which you obviously can do).

Most modern Liquid/Air IC systems will have a seperate resevoir. And yes, ice can be used to drop the temps below ambient. Here is the resevoir I used with the following. I even had a hold for dropping dry ice; near freezing IAT's on a 70 F day.

Pretty cool. That is on an Acura TL? Or Honda Accord? What PSI boost 7-8psi?

[maui86]

im sure when a 400hp 335i hits a good track with a experienced drag racer, traps should be good. you'd be surprised how slow some people shift thinking its still fast. especially in a turbo car, its pretty damn important.

for example...there is a guy where i live who takes his 07 zo6 to the drags and doesn't know how to launch or shift and does 12.8@117 or slower(friend who has an auto ls3 vette does 12.1@118 consistently) ...his friend jumps in the z06 and does a 11.7@124mph his first and only run. i think you simply have the driving edge over most of the guys here...i wouldn't be surprised if the 335i is the first turbo'd car that many people on this forum owned/driven. so people are still learning...i will be honest and this is the most powerful car i've owned, and first turbo'd as well. so when i get to 400hp it will be a learning experience given i have a 6m/t.

continue with the testing and keep up the good work, i really like to see what this car is capable of and you seem to have the skills to pull it off.

2003 CL Type-S 6MT running about 7.5 PSI which was enough for 369 WHP. Great engine, just the wrong chassis; FWD and higher power sucks.

And yes, the VTEC chnage over occurs at 4800 RPM.

[hotrod182]

Damn any torque steer on that Acura? LOL.

I did some runs on the new 8A map this morning.
Same exact configuration I did the 108 mph runs on stock boost.
115.7-115.9 mph now. So about 7mph+ faster, or about 70hp or so. I would estimate my RWHP to be somewhere around 340-350hp. Not bad for 91 octane. This car is getting faster and faster. I remember with the same set up on 1.3/1.2 Beta I had a hard time getting 115.2mph. Traction kind of sucked this morning. I tried launching in 2nd gear and the tires just broke loose and the car pitched sideway violently with the Hoosiers!
