Walked U

I was contemplating on doing a custom gt37 single turbo set up on my car but theres too much stuff I have to do on top of it thats not out for the car yet.

Meaning theres no injector upgrades, spark plugs upgrades, fuel system upgrades just to name some.

Most of my stuff is custom that my fabricators shop made. We already know theres not enough room to do a twin set up. But if you relocate things like the over flow reservoir and take out the stock air box you have tons of room to work with.

Its all a live in learn situation tho. Doing a custom set up would cost a lot more than waiting for a production piece to come out also your going to be ending up doing your own R&D.

Walked U

Yup, fueling is probably going to be a problem but im not sure if that either.

I have a few friends that are techs and engineers for bmw and theyve said that we are only using 50% of the stock injectors capabilities. But I dont know if they was saying that in a stock car or a tuned car.

I could do nitrous also theres some people doing that.

Walked U

Yes theres a few people that are doing it. Only 1-2 i know on the boards that are doing it.

I believe one guy in south FL is running full bolt ons and a 50 shot. I think he has a tune for richer AFR's for it tho.

And how much whp does your car have?

Walked U

Im running on cali pump gas. On 100 octane I make those numbers.

On 91 im more close to 390-400 rwhp and like 450-460 wtq. Theres no race gas map for the procede so we just have to depend on our cars adapting to the octane itself. Usually its about a 20-30 rwhp increase by going from 91 to 100 depending on what mods you have and the adaption time.

Walked U

Thanks

Yup, marks car will needs to get tuned. Its basicly a stock e55.

Ya on the 3rd run you can see he let off after the merge.

I have more done to my car than jon's.

Ive spent a bit doing my own R&D on pieces.

Ive went through about 5 exhaust systems and down pipes which cost about 7k.

Ive upgraded both cooling units and done all the little supporting mods just to make the car more reliable in my eyes.

Performance wise tho, all I have is DP's, FMIC, exhaust, drop in filter and a few light weight mods.


The rest are just supporting mods that help my car hold the power and sustain it.

I haven't dynoed my Current setup.Previous best was 341whp /417wtq on a Mustang dyno.(reads lower then others) by comparison a stock 335 makes about 250whp 270wtq On the same dyno.

Carl Lassiter

20-30whp. Sheesh, there's a place around here that sells the stuff. May have to check it out. Usually though, got to put up with 91. We need 93 out here and I just don't understand why we don't have it.

At work so haven't checked the vids but I'm assuming the M5 is faster the higher the speeds. Well done on getting such rwhp though.

What are you doing about your warranty?

blackbenzz

I'm pretty sure that goes out the window when you start modding.


Walked U- If you guys are only at 50% of your injectors capacity, why dont you just turn up the boost? Or are the turbos maxed out?

Walked U

Ya 91 sucks. Theres a place that sells it here also, its like 10 dollars a gallon tho. hahaha

Ya 93 would be nice for DD.

Im going to put in a meth injection kit next so I dont have to deal with getting higher octane anymore.

Ya on the first run where i ran the m5 in 4th i boosted 10 psi instead of 15 and he was killing me after 130 mph.

On the 2nd run 40-155 I stuck it out with him til my govoner but then my car bottomed out and I had to stop.

thanks a lot

I think he said before that the turbo's are maxed, and that there's no way to do a larger twin setup. Basically you're stuck going with a ground-up single system and hoping that you're not overtaxing your injectors. Sounds like fun.

I guarantee you someone in Japan is doing this as we speak. Signal Auto or someone else.

blackbenzz

Oh ok, maybe next time I should learn to read before opening my mouth

Walked U

Ya, im pretty sure if you mod then warranty is gone. But as long as you dont go in with something broken they wont void it.

Ive been in there a couple times already and i get compliments on my car.


About the injectors and boost. I heard from a tuner that the car is capable of doing 450 rwhp on race gas after that the turbos and or the injectors are maxed out.

Theres suppose to be a map coming out that allowed 400 rwhp on 91 octane with just a procede v2, exhaust and DP's.

No word yet on a race gas map.

Walked U

Oh also, we dont really have the choice of upping the boost like a manual boost controller.

Usually just maps are released and have a set boost target. But sometimes there will be a glitch with it and some people end up exceeding the limits.

Theres a few people that have taped 21 psi on the turbos before.

Ive had a friend back east over boost to 21 psi on the dyno and end up making 478 rwhp but the car was knocking hard on 93 octane so he shut it down and went to a different map.

wonder how my fully bolt on M3 with 4.10s will do vs the 335i.

and when i supercharger it in a few months. =)

im guessing ill lose by about 2-3 lengths now and when i add the blower its gonna be close. theres vids of the VFE kit on an E46M3 that not only hangs with but beats a E60 M5 with a couple mods.

Walked U

Ya thats my buddy Drews car.

Hes in the works for beta stage 3.

I think hes making liek 500+ rwhp now on 100 octane. His car is very quick. All the little bolt ons with 3.91 gears and meth injection.

TopGun32

one thing I just noticed...watching the video once more..

I did not know Mark's black E55 had aftermarket wheels.. not sure if they are 19's or 20's.

Recently Vadim (VRP) respectible tuner.. dyno'd a E63 with 20's and lost hp and tq across the board. He dyno'd 380RWHP and very low torque figures. As soon as he put the stocks back.. he dyno'd 410RWHP+.

Once reason the E55 is a bit quicker than the CLS AMG's is due to the weight of the wheels 18's vs 19's.

Maybe Mark's car is running with more power, is unable to put as much due to the wheels.

just an observation. The same can be said for the boosted 3 series.. heavier wheels not race friendly.

Walked U

Hmm true. I run on 19's instead of 18's now. But also Im not running the same stuff when I ran the cls55.

When I ran the cls55 I only had 364 rwhp and 410 wtq, with full stock weight.

I did run that cls55 like 6 months ago or so.

blackbenzz

Size is not as important as the weight of the wheel. What wheels are you running?

Walked U

SSR SP1's they dont make them for my car or offset but the last owner of the wheels fabricated them to work.

19.5 lbs in the front and 20.5 lbs in the rear i believe.

19x9.5, 245/35/19 (rubbing )

19x10.5, 275/30/19 Bridgestone potenza RE750's. They are pretty stretched out.


Sorry this is the only pictures I have of them.

blackbenzz

Those are some light and good looking 19's!!! They weigh about the same as my 18" kinesis wheels!

Walked U

Thanks a lot. Im thinking about going back to 18's myself. Yours look like 19's for a min hahaha, very good looking wheel. If I go back to 18's im looking for some kinesis.

I hate how theres no DR option for 19's. Rather get some nice 18's and put some good tires on them instead of going back and forth swapping them out.

blackbenzz

Thanks. Well thats exactly why I went to a light 18". The wheels in my sig are 19" DPE S20's but I'm usually riding around on my 18" kinesis K18's with RA1's out back. For a while I was riding on BFG d/r's in the back

That is one bad 335, nothing like turbo injection and a nice tune..
