that sounds very exciting and fun.

but expensive and sacreligious at the same time. i dont know why im so scared to cut up anything of the existing system. what about a suprcharger? tuning and fab work will be alot less than doing the turbo. and boost will be from 1000rpm. erm remind me again why people do turbos instead of superchargers? i know about the fact that the supercharger uses power to make power. but with all the problems turbos cause, isnt it better to just do an sc. i know of some sc that makes 20psi. does one really need more than that?

i got home 2 a nice surprise. My t3/t4 just arrived. I cant believe how fast they shipd. U cant beat the chinese in business. But im going 2 sell it. I found an eaton m45 for cheap frm a scrapyard. Came off a c180k. Im so super stoke :-) but i have 2 admit.that t3/t4 is begging 2 go on my benz.

using a supercharger with your jetronic will require some modifications. you will have to figure out how your going to route the supercharger without affecting the stock jetronic system. its more work to the intake side of the engine whereas the turbo would be more work on the exhaust side.

superchargers are great for off the line power as they are pulley driven there is no lag to worry about. they however make less power as you will loss 20-30% of the power due to actually turning the supercharger via crankshaft pulley. they also have a linear power band. as rpm goes up so does boost. you dont get full boost at lower rpm like a turbo. they are also limited especially the roots type blower you are looking to buy as there is no cooler. some come with coolers but they are still using engine coolant instead of ambient air to cool the fluid so heat soak is an issue.

turbo chargers can be more flexible to the owners need. there main disadvantage is lag. there are many variable displacement turbos out there that can alleviate this issue but there pricey. they cost a bit more to build. there are many advantages. make more power because there exhaust spun instead of crankshaft spun. upgradeable. allows for efficient intercooler cooling

ok.u are very convincing. And so is this huge ass t3/t4 next 2 my bed staring me in the face every time i wake up and go 2 bed. Tell me,how effective is an fmu? My car comes standard with a vacuum fuel pressure regulator.i have askd the guys on a mercedes forum wrt its limitations. And what sort of device could i use 2 measure afr? A wideband o2 sensor?

fmu's are effective but there not a tune. the exponentially raise the fuel pressure based on boost pressure. there is no fuel control with an fmu.
you will need a wideband afr gauge. all you need to do is weld an o2 sensor bung in the exhaust to accomidate the wideband o2 sensor and then mount the 2.25" gauge in your vehicle. i used an a-pillar gauge pod

ok.i wonder if my local hardware store keeps them. Do u know of a good source online?

i got mine at a killer deal on ebay. go with a quality sensor/gauge. i went with auotmeter.

ok gr8.i wil look 4 it.thank u so much 4 ur continuous support

anytime

i found an autometer o2 sensor on ebay for $107. does this come with the guage? or is it just the sensor? its supplied by a company called collisionparts or something
