Turbo delay.

[Metalli<a]

is there a way to get turbo delay 100% gone on a mercedes 2.5 liter desil turbo?

You should try the forum for your car. If you are talking about turbo lag, then you could use a really small turbo like a T-25. I don't know what line of turbos mercedes uses, but getting a smaller turbo will virtually eliminate it. 100% gone, probably not. Noticably gone, more than likely.

ok i see thanks, if any others can give second of third opinion i would appriciate it.

Turbo lag can be the cause of alot of factors:
1. Engine size
2. Turbo size
3. Exhaust
and the list goes on...

A bigger engine will spool a turbo faster, a smaller turbo will spool faster, and the less restrictions an exhaust system has will help a turbo spool quicker.

Is your boost lag a serious problem, or do you just want the constant power of an NA... because if you do, you might have gone w/ the wrong car...

humm worng car? i dunno man all i need is some turbo lag gone, i dont think its impossible. you also say less restrictions on exaust system, im not quite sure what that means this is my first car im gonna put mods on. the only thing i really know about is how engins work, i really dont even know what a turbo does exactly. iv also heard of super chargers are they the same thing? or can your super charge a turbo? man i got no clu someone help me out. whats a turbo kit do exactly and whats a cupercharger? how do i make this desiel own in a race?

The only way I know of to completely eliminate turbo spool time, or turbo lag is through the use of nitrous. You can use a very small shot to inject into the intake charge and help spool the turbo. However, this introduces a new problem, traction issues.

This will also get better responses in the forced induction forum. I'll move it there.

"i dont think its impossible" these gotta be another way than a nitros system i dont want to buy. traction on a MB is great (not in the rain iv got too much torque) only slid once in the rain dooing something retarded. i plan on getting new weels and rims anyway, strut bar dont sound bad either, so some of my questions remain...are super chargers the same thing as turbos? or can your super charge a turbo? man i got no clu someone help me out. whats a turbo kit do exactly and whats a cupercharger? how do i make this desiel own in a race?

ok you deffinately need to read the turbo 101 and turbo vs supercharger threads at the top of this forum.

also check www.howstuffworks.com and find out how a turbo works and what it does.

a less restrictive exhaust system means you want a big exhaust pipe like 2 1/2 or 3 inch in diameter from the turbo back and if you want to be legal you should put a cat and muffler on there too but try to get those the same size as the exhaust pipe. this will allow the exhaust gas to out of the turbo faster and therefore spool faster. you also want to put a less restrictive intake, i have found that a pvc pipe and an intake from the import isle at autozone work fine.

ok first things first....superchargers and turbos are completely different...turbos are basically "free horsepower" meaning it doesnt take any power to drive one.....it is driven by the exhaust to force air into the motor.superchargers are belt driven and it takes horsepower to drive one....this is a poor example but on drag cars it take i believe 600 hp to drive the supercharger on those cars(correct me if im wrong). all i can say about this is to read up a little about each of them and youll understand wut ive said a little better.

as far as freeing up some lag that youve got....you should have plenty of room to run a 3 inch exhaust system....for turbo cars you want to open the exhaust as much as you can....you lose a little bottom end but you turbo spools much faster thus making your power sooner and longer through the power band. you can also remove the cat or get a high flow cat and a straight through muffler.

if your car has a MAF sensor it might have a screen in there....if so you can remove the screen and that supposedly good for a couple more pounds of boost. also get a k&n drop in filter will let the air get to the turbo a little easier.

I don't think a diesel, will ever do that great at the strip, unless it is much larger or has lots of money in it. It probably doesn't rev very high, even if it is a mercedes td. I have gotten beat by a Powerstroke F-250, but it had tons of money into it. Diesels are not race cars normally.

[Metalli<a]

ok well its rare that a desiel races that one of the reasons i wanna race this one to be diffrent u know. i actuall have seen a benz 300D with body kit rims and prolly allot under the hood. it was freakin loud as $#!+ and hauled ass. it looked like it could own pretty badly. it revs quite nice i may add, so tell me. if i get a bigger muffler system the turbo will "spool" faster? ok thanks guys your really helping . what else can i do to this monster? and another thing would dual exaust system bigger help even more? and someone said something to me about a blow-off air intake? what is that?

dual exhaust most likely wouldnt help much more...not worth the extra money in my oppinion. someone said something about a blow off air intake...they were referring to a blow off valve...you could get one but it doesnt do anything performance wise...it just saves your turbo.

obviously youve never gone to cummings website...i belive they havea 9 second drag car thats diesel. and ive seen videos of a 12 second cummings powered dodge ram that was extended cab dually long bed....ver big truck and it even had a 6 speed tranny which suck for accelleration.

[Metalli<a]

ok, thanks. in another post or maybe this one, someone said to get a smaller turbo as well. a t-25 if i remember right. a smaller turbo spools faster, thats good, but does it give the same horse power? probally not im guesing but will the car go faster is it a speed power tradeoff? a smaller turbo spools faster ok but in the long run is that better than a bigger turbo?
