Opinions on Mosselman Turbo systems

[eeeks]

I ran into an old buddy of mine who has a benz c280 equipped with a Mosselman kit. Looked to be a very clean install. Power was quite a bump up from what I remember his car to be. An an automatic too.

Are there any opinions on the Mosselman kits available for BMWs? This could be something I would do in a heartbeat if quality and reliability are what they seem.

I know their website says that they're great, and at one point I think Turner used to carry them. Korman still does.

Back in the days of bimmer.org, on the E36 board there was a user named *DM* who was getting one installed in his auto tranny e36. Does anyone remember this?

can anyone help out?

Thanks all!

Korman wants to only do in-house installs.

The kits aren't cheap. They also don't use software, just a boost sensitive FPR. They are good from what I've seen of the them.

Thanks WJones!

Does anyone know of anyone else running these kits in an E36? And...if I do get the kit, can a competant mechanic do the install?

Since it uses a FPR, what kind of tuning issues will I be facing, as there is no custom programmed chip per se?

And...Would it be detrimental to run this turbo kit with the currently installed Jim C software?

Thanks in advance all.

If there is no software with the kits how does it retard timing while under boost ?

If I remember correctly, AA is a Mosselman distributor. You might want to check through them.

Yes, it would.

If it remember correctly the kit provides colder plugs to retard the timing. Max boost is only 5.5 or 6 psi.

Maybe I misunderstand you, but since when did colder plugs retard timing? Perhaps, they may delay detonation a bit, and thereby 'influence' timing by delaying retard, which of course, is the opposite of what you are saying. You say they would retard timing..IM saying they might delay Retard... But cold plugs dont retard timing...Even if you want to make a case for them influencing timing at all, then their influence may be felt by allowing a slight increase in timing advance prior to any knock detection, but certainly they will not cause the timing to be 'retarded'.....

As I say, maybe I misunderstood what youre saying, but taken literally, this was my response. I think the answer to M3TurboCAs question is that a RRfpr, if successful at providing an adquately rich mixture, can fairly successfully stave off detonation, especially if boosted to under 6 psi. If need be, there's always the knock sensor to handle any situations where knock is introduced. But the key is in keeping the mixture rich enough via rrfpr. Dont forget, a certain amount of retard will occur in response to elevated IATs, which invariably result from the compression of the intake charge within the blower.

Sorry, late night post... delay detonation is correct.

So if I'm reading this right, Mosselman's approach using a FPR is okay in conditions under 6psi, which I think is the output of the kit. Does anyone here know of, or have first hand experience with this kit OR just using the FPR route to address fuel delivery and detonation issues?

Yea....the ERT kit for OBDII featured just a rrfpr to handle fueling...no new injectors, and no software was included in their kits. They seemed to run pretty well. rrfpr is nothing new...its main reason for existance is to provide fueling needs for cars under boost.

Thanks for clearing that up for me. I appreciate all of your feedback!

But...

Methinks the wallet is gonna be hurting REAL BAD soon
