took car for tuning to day. lil problem
I called the tuning shop around lunch time and the told me that the boost controller and the car spiked at 15 psi on stock block. He said the trans sloped alil. Should i worry?
|
ya, your head gasket leaks now
|
Hey just text me he tuned it to 11 psi at only 245hp :(
|
probably went way low on the advance
the rods break only a bit beyond that number one good question is are they even using the GM 2 Bar Supercharger tune as a base? if not he's using an inaccurate scaled 1 bar setup... |
I asked the same q's b4. He's using the 2 bar. This guy has 2 ld9 grand and one pushing over 430 on meth.
|
shouldn't need methanol.
if he supposedly has 2 LD9s and knows how to tune them, then something may be wrong with your car. running an air filter? could be clogged could have a boost leak could have exhaust leak pre-turbo exhaust piping too small (what size do you have?) do a compression test then again, you have an eBay journal bearing turbo that is about the size of a genuine GT35R. also the auto trans slipping will cause a lower reading. and if they're using a mustang dyno it will also be lower than what you might expect from a dynojet or others (by 15-20%) |
Your right. He says my tb gasket is leaking alil. He advised me to go to a 3" exhaust with no cat. I'm using a 2.5" exhaust turbo back with cat. In va and need to pass emissions at the end of the week
|
Compression test for sure.. Also like ion said if it was a mustang dyno your numbers are going to be really low
Wait till after your test, than do the exhaust work lol |
That numbers am I looking for on stock block for the test. 125-150?
|
Somewhere between 170 and 190.. but the more important thing is that they're all close to each other. And above 150.
|
Unless you crack that 400hp mark the 2.5 inch will flow just fine. Getting a 3" over the rear arm is next to impossible, not impossible, but its going to hit. If you think the 2.5 is not enough I would invest in an electronic cut-out.... just my 2 cnts bud
|
This is a turbocharger we're talking about, not a supercharger. Just because it "might" be able to flow fine, doesn't mean you can't make it bigger. No harm in going huge on a turbo exhaust.
2.5" exhaust to 3" open downpipe is a massive gain on my vehicle. |
Did you manage a 3" over that rear arm? Hell man, seems like every month Im adjusting mine and its only 2.5
|
(C2) Do you have a 3" full exhaust
|
I said open downpipe. It's 2.5" all the way back after that. But yeah, fitting a 3" all the way back is easy. I will do a mandrel stainless soon. For now, opening the downpipe is what I do at the track.
|
What I have heard from many people is that e-cutouts Tendto break and stop working. No personal experience just word of mouth.
|
Yep so use a manual one. For me I have the downpipe connected to the rest of the exhaust via v-band. It's as easy as unbolting a clamp and hanging the rest of my exhaust on a second hanger next to it.
