Need help after E1 install - SRT Forums

OhSnap · 05-13-2008, 11:17 AM

I installed my E1, everythings tight all vacuum lines are secure and nothing leaks. The boost gauge is only reading about 3 pounds of boost when I rev it up, I dont get it. I have an AGP wg that might need to be reajusted but can it really be causing the turbo to only boost 3 lbs? Can someone help me? only reasons or ideas it is boosting this low? Thanks

Can you feel the power loss when driving or is it just the boost gauge???

When you say "rev it up" does that mean your doing a pull or are you just reving it up in neutral?

yeah that^^^^^^

No just in neutral, I'm too scared to drive it. The boost gauge was fine the day I did the install and now its not pushing past 3 lbs at about 5k rpms. I think it might be the wastegate but I guess I will find out tomorrow.

If the wastegate isnt opening then what would that do?

Ummmm, the car will not build alot of boost really while sitting still.

Maybe if you had a 2 step it would but you didn't say you had one.

First take the intake pipe off the car (do all of this with the car turned off). put your finger in to the turbo and check to see if the turbine blades spin freely. If they do then maybe do a boost leak test (which should be done anyway after doing any work on the car that requires messing with boost related items). After that slap everything back on and take the car for a drive. I would actually recommend lower the boost on the AGP wga first before driving it.

This way you do not boost too much and possibly cause a lean condition. You can always boost too low and raise it back up with no repercussions. But you can not always do the opposite.

Detonation is bad.

Also, if you can afford it later, look into swapping the AGP wga for a FM wga. Trust me, you will like it a lot more.

Post back when you get some results from the suggestions in the thread and we will try to help you out.

Turbine spins free as as hell. I checked it when i got it, 2 weeks ago, 1 week ago, and the day I installed it. I actually tore the bitch apart again after this started to check it again and it still spun like a charm which is why I'm so fucking confused. My list of things to check are the wastegate and the charge pipe, but I really think its the waste gate (as I doubt the charge pipe would cause this MASSIVE amount of boost leak). I know what you mean about the FM wg but lord I just want this bitch to spool up to the 17 I had the stock turbo hitting before I start buying more parts. Hell, I had to pass up a great deal on an exhaust because of this.

Another thought. If the wg arm is all the way to the left or right, is it possible that the flap is staying open or closed and thats why almost no boost is happening?

Have you driven the car yet and tried boosting?

If so is that when it is getting the 3 psi. Or is it only getting 3 psi while sitting still and you reving the engine?

Yes the charge pipe can cause a huge boost leak if the clamp going to the turbo and chargepipe isn't sealed well. Trust me I learned the hard way. Got myself a 2.75" t-bolt clamp to replace the crappy worm clamp that comes with it and it sealed it right up.

Yes, if the arm is too loose on the wga then you will only hit a few psi on the turbo and the lag will be tremendous. Tight it up to where there is tention on the arm and it doesn't wiggle around or anything and then give the car a try and drive. Then if it is still too low, tighten it again some more and give it a try. Unfortunately it is trial and error until you get the boost you want but in the end it is worth it. Make sure you pay attention to your A/F ratios as well though while upping the boost. Do not up the boost past what your fuel system can support.

You have a bigger wheel in the e1, your not going to build up as much boost by snapping the throttle like you use to. I dont know why your checking your boost in parked and in neutral. Go drive the damn thing. Just make sure you break in the turbo before you smash on it. FM should have gave you a procedure.

OhSnap · 05-14-2008, 11:34 AM

Im going to go drive it today and try adjusting the wg arm and check the charge pipe. Let you guys know.

The wga should be pulling the flapper pin to the right (closed). It should be pretty tight. Drive the car and continue to tighten it until you reach your desired boost level.

I think i met you at one of the meets last summer, but if you cant figure it out your more than welcome to come over and ill take a look at it for you.

Remember there is no load on the engine so it's not going to make alot of boost while sitting in neutral. Most turbos won't even make boost while in neutral.

OhSnap · 05-15-2008, 04:37 PM

Yeah you guys were right but something still doesnt feel right. Under load it is boosting to 14. The car seems slower though and boost seems to be creeping on slowly (and I mean creeping). The wg is only set to 14 and I will probably turn it up in the next week or so to see if I'm just delerious or not.

Civiceater, I'm the guy with the silver that you met off 413 about 9 months ago. I just might have to take you up on your offer. PM me and let me know what your schedule is. I probably wont have much time until next weds or thurs.

You said you did a boost leak test right? Is the fitting where the blue line use to be capped off? A leak could cause the slow building of boost. You also have a bigger wheel so it will take a little bit longer to spool. Especially at lower boost levels. Check for leaks and turn up the boost. Let us know what happens.

Do you have a scan gauge?
