Wow, Gary D is posting here now? Cool.

For you that don't know it, Gary Donovan is the God of Turbo Mopars, sort of like Buschur to DSM's. The two engines share a lot of common traits, so everyone could learn a lot.

I think the dodge engines are blessed with more displacement and lower compression, so they can run higher boost. I've never understood why 1G DSM guys switch to the higher-compression 2G pistons....?

someone correct me if i'm wrong but, i belive 2g pistons are stronger than 1g pistons, and it's cheaper than going with a aftermarket set?

yeah the mopar turbos came in 2.2L and 2.5L don't know the compression but it seems the 2.2 blocks are better.


btw i belive gary donovan runs 35psi on his reliant

hmmmm. having wet dreams about 35psi :)

A friend of mine (mechanical engineer) is modding an 89 Shelby Daytona, and we both have learned much from Gary Donovan. I think the best way for the 5th injector would be to control it off of 02 voltage, and find a way to regulate the injector keeping the 02 at .91... Gary, those daytonas sound amazing and SUPER loud with that 3in straight through exhuast, cops came to my friends house. They are badass cars. oh, and the compression for the 2.2l dodge 4 is 100psi.

we need to get back on track or I'll be locking it,

Just start a new post if we are going to talk about 100 PSI gauges. ( also not in this fourm )

Also Gary, telling people that your running 100 PSI of rail pressure isn't enough, you should also inform them that this can cause the injector to lock up ( Lock open or closed ) or blow out a O ring and set the car on file. The whole truth not the half truth. ( and IMHO you shoule be running a larger injector if you NEED to run 100 PSI of fuel pressure ) I'm not saying that I don't think that your correct it's just there is more info to be given and just saying one thing and not outlining the risks that are taken is a poor way to give info.

IMHO pushing a injector past 80 PSI of rail pressure under boost is getting a bit scarry for most people. For someone like you that will be able to deal with a car that has been bruned to the ground, this is fine but most of the people in here are daily driven car and do not know the limits of the parts on the car ( Let me say safe limits ). Just give all the info not just half ok. ( or I will post more like this :) )

All in all I see you have been a good help to some. Keep it going. I have seen your page, nice work, some real street terrors in there!! :D

Thanx

Never seen it happen.

Whats wrong with 100 psi of fuel pressure? at 30 psi of boost thats only 70 psi AT THE SEAT of the injector which is what the chrysler/bosch injector is rated for, been doing it for over 10 years now with no failures, ever.

In an ideal world yes it's better to have higher flowing injectors and lower fuel pressure but at high boost you WILL always have to have fairly high fuel pressure to overcome boost in the intake, fact of life.

I'm not saying that I don't think that your correct it's just there is more info to be given and just saying one thing and not outlining the risks that are taken is a poor way to give info.

Again, in the real world I have never seen what your talking about- what your referring to is is all theory.

IMHO pushing a injector past 80 PSI of rail pressure under boost is getting a bit scarry for most people.

really? why? at 30 psi of boost thats only 50 psi that can be used to fuel the engine.

For someone like you that will be able to deal with a car that has been bruned to the ground, this is fine but most of the people in here are daily driven car and do not know the limits of the parts on the car ( Let me say safe limits ). Just give all the info not just half ok. ( or I will post more like this :) )

I take the correct precautions when dealing with high pressure fuel systems and I would assume anyone else looking to run 11's, 10's or faster would do the same.

All in all I see you have been a good help to some. Keep it going. I have seen your page, nice work, some real street terrors in there!! :D

Thanks! I try.
