How much boost before I blow up the engine?
Are there any people out there that know the boost limits of yall's E55s?
The reason I ask is I'm building a remote turbo E430 and I want to have a good idea of the maximum boost I can run the motor at on pump gas and no additives. I already have a 400hp daily driver e320 running 11-13psi (499whp at 18psi with water/meth inj.), but I'm tired of the weak 1st gen 722.6 it has. Plus I need more V8 music. I'm going to use the LET tuning equipment on it to reflash the car and I'd like a good idea of what psi I can run the stock motor at. I've seen a lot of 500 and 55's running 7.5 and 8.5psi but I'm hoping i can at least run 10 as I run the E320 at 11-13 all the time on 92 pump gas. Let me know! I'm itching to get it done and post up another epic(to me
) turbo build thread

Yep, it's a rear turbo. I finished fabbing up that exhaust a long *** time ago. Dutch has the car sittin on the lift with the turbo installed on the exhaust and he finally got the oil lines on. The car is 2nd place to his 468 camaro dragster unfortunately so his progress has been slow.

430 is a high compression engine, most the data on boost is to be found with people that did the HPS conversions years ago. I remember 6 psi with out any cooler. Claims of performance were OEM 275 @ crank, 350 @ crank with HPS supercharger. The 430 has cast pistons so detonation is your limiting factor. Very interesting project Max, pics would be nice. Did you maintain the dual exhaust to a twin port Turbo?

You made 499whp on the E320
You need to drag that thing.
In terms of LET tune do you mean some handheld unit they were talking about in another thread or are you having them dyno tune in house?

Yea the m104 is arguably one of the strongest built mercedes engines next to the m103(its made 650whp on a stock motor thanks to PUMPISH and his megasquirt standalone).
My m104 is all stock and yes timing is an issue, thats why I use water/meth injection when I do my high boost pulls. When I did the 499 pull I thought I was going to do die, I was so worried I was going to pepper the head or blow a piston but the engine was fine and is still smoother than a babys *** on the inside after a shop towel wipe down:
The m113 has a stronger iron coating on its cast pistons v. the silicon on my m104 pistons so I'm not too worried. I hope to rent the LET computer to adjust the timing and fine tune the fuel maps for use with E55K injectors and a BEGI FMU.
You said right Yacht Master. I utilized the stock dual exhaust pipes and mounted a divided T4 flange for use with a divided housing Masterpower T70 turbo. I remember seeing the test on the HPS E430, 6psi and non intercooled on stock injectors and what not is very promising. The TT kits for the early m104's ran 7-8psi on stock injectors and with my mustang cobra injectors I more than doubled that. Just think of an intercooled E430 running 12psi. Its already going to run cool with the turbo in the rear by about 150 degrees but with a small intercooler up front its going be sucking in damn near ambient air temp.
I'll post the pics and build thread of the e430 when everything is done. I need to finish this before I turn 20 in February just so I can say I was a teen when I did it A turbo E320 at 18 and a turbo E430 at 19

I hear about that too the M113 4.3 have the biguest compression rating maybe you can run at 6 - 6.5 psi (Supercharger +/- boost). you can replace the pistons with some IASA forged or low compression to reach 10 - 12 psi Exellent project

I'll get some good ones of the car on the lift soon. I'm going to boost the E430 at 8-9 psi with some E55K injectors and with the timing advanced pulled out of the ECU. Just like the E320 this will most likely be done in July or August. If all goes well with the 430(goes well= 400whp +/- 25hp) then I swap a m113 500 in the 430 and see what it does with the extra horspower and lower compression.

I know TWO turbocharged C36's that r running that much to the wheels with standalone fuel management(controls both Timing and Fuel) and FMIC.

I'm using the smallest front mount available lol its like 30"x7"x2.5" It doesn't heat soak though. I've got it damn hot only once(engine temps climbed to 95-100 C from the normal 81-83 C after the 2nd attempt to hit 500whp). For engine management I'm using the AEM F/IC. It controls the ignition and fuel directly through the cam and crank sensors and the fuel injectors so its impossible to defeat. Its a stone's throw away from a standalone and only $350. It's better than the much more expensive Greddy eManage and tested as so by several magazines.

I never got any times before the tranny blew(cant shift without slipping with full boost) but when I go to the dyno here soon I'll give a fresh dyno sheet posted for my DD settings.
I have an OLD dyno run when I lowered the compression and ran 9 and 10 AFR's lol it was WEAK. It was between 9-10psi running extremely rich.
\/
I will make the excuse though that my car weighs 3605lbs and they had it set for 4000lbs(you notice how slow it accelerates...) so thats another power downer... I'll never go to a mustang dyno again lol.

You mind showing us a dyno sheet. I have an AEM in my Talon. I'm very familiar. The AEM F/IC I know nothing about. How you were able to get 499whp with such a tiny intercooler and not detonate,stck injectors I'd assume,has me wondering how. 18psi boost you say? Interesting. Forgive my skeptisism but even in the dyno vid you posted in the kill section you posted 310 rwhp and 330+rwfttq @ 10psi 9.0:1 compression. Which I could believe. How you got 150more whp is my question @18psi.
Video:http://www.youtube.com/watch?v=3dCFM0qa67o
Because I have a $9500 car vs. $20K and up cars...thats why. I could tune my E320 past 600hp if I wanted on the stock engine with some head studs whats your point? A B5 S4 is like a 260hp car stock....
Did you miss the 499whp with water/meth injection at 18psi? Spot those car lengths audi man.... Why are you on this site?

If you have please post a dyno sheet and a list of your mods. Thanx!
11 sec modded W211 E55K's put out that kinda power modded.
Like I said forgive my skeptisism just want to know,and continued success on your project!

Yea that video was the weak *** dyno I was talking about. That's the reason it backfired on the way down, my car never does that when its tuned right.
For the 499 pull I used a water/meth injection setup like Blown_M104's seen below to keep the motor from detonating. The small intercooler does not cause it to detonate, a bad timing curve and a 100+ degree temp would.
I'll show you the new sheet coming up in a few days, as the original 10psi sheet is embarassing(it look like the rocky mountains). The only sheet on my laptop is this 11.7 AFR tuned 6psi pull on stock compression(pictured below) that became subject to TB shake. 278hp/311ft lbs of torque,. What happens is the boost smacks the TB and the return spring can't hold the TB plate WOT but I've since fixed that lol:
For 600hp I wouldn't use my turbo, I'd use a GT40 or 42. Its proven that a stock M103 with studs can hit 650 at the wheels with an adjusted timing curve and redline at 22psi with a GT45 turbo. The M104 flows WAY better and has the same forged and cast components as the M103.

I would agree the M104 engine (especially in C36 form) is an absolute monster... shame nobody ever really pushed that motor to its limits, it could have supra like power if put in built properly with the right tune and you lowered the compression a bit. A much stronger aftermarket head gasket would have to be made most likely since that's the real achilles heel on that motor, other then that its a panzer tank.

HELP WITH BOOST
Just wondering how the e430 w210 boost build is going, like yourself i want to be able to boost my e430 but am very alone on this topic as a lot of this stuff isn't common in Aus. What was the process you went through to get it all done eg ( Turbos, injectors, Ecu) etc. Not looking for too much boost as i know its a high compression motor (btw ive seen the CR as 10 is this true for an e430?) if you could please shed some light onto this from your build as it sounds very interesting and reliable.
