Evo X upgrades

[mlomker]

I would guess the MAF is taking a dump. I have heard quite a few people have had failures with them...warranty!

You'd think so. I ordered an ETS intake in case I need to swap it in. I like it better in some ways.

I'm getting close to having to park the car for the season. Too many miscalculations on this project.

I'll be sure to give you a ride in my car when it's done then ;) (knocks on wood)

I really doubt the AMS intake has anything to do with the prob, but it is possible. You should find the problem before ordering more parts man, lol.

It's either the MAF or the intake. Swapping your intake in wouldn't help if it's a design issue, the ETS looks like a good design, and trying to borrow someone's intake for a week (since I don't know Shane's schedule) is tough. If it's the MAF then I won't install it and just get an RMA for it.

I couldn't imagine a dealer being willing to warranty anything on my car. It wouldn't cost me anything to ask at Brookdale, but...

The fueling problem is the bigger issue. afaik the MAF is just preventing me from making more power than it currently has. I'm hoping to hear from LJ today...maybe I can bring it in and have him take a look see.

True on my intake, did shane try my MAF though? He asked me and i told him it was fine.

My car parts are free game for testing until it's time to use em :)

Yea I sure hope LJ has some ideas, it sucks that so many little things keep coming up for you preventing the big overall picture.

He hadn't when I spoke to him last night but I told him that it seemed like a good idea. Def appreciate your help. This stuff is starting to get me down, for sure.

I had a track day on the 28th pre-paid...hopefully I can get a credit or refund.

I like the maf-swapping theory but how does that explain why it behaves differently in a straight line vs turning? To me that is a fuel system problem. Find a stock fuel assembly stat, put a single walbro in it and eliminate that whole twin pump setup from the equation.

[Murlo26]

^Good idea..I'd say give LJ a shot...otherwise throw your old 255 setup back in and have DB throw a boost a pump on it. I am actually considering switching to a single 255 with a boost a pump to simplify things. After seeing how many issues you have had, i want simple.

Bingo.

[Murlo26]

We are talking about two separate issues...their is a fuel line pickup problem on turns, mainly left turns, which is present on the X stock if you road race, but seems to be worse with lomkers hangar setup. Then there is the MAF reading 4.9V and basically being maxed out...which to our knowledge shouldn't be happening since as far as we know, the stock MAF's were used on much bigger builds, for instance Ryan Gates and his 566whp setup which was still the stock motor.

I know its a little uncivilized maybe, but maybe an inline 255? its been proven on DSMs for 700whp on E85 thru stock lines.

I know its not using a baller piece but it gets the job done, and just throwing this out there, but I'm going to assume you can't do a 1g style twin pump setup?
