well ive been quiet for a while now but after getting a custom built turbo installed, the tech blew the engine while tuning with the interceptor-x. the air fuel ratio was at 18.

 

sorry to hear about the misfortuanes, if you don't mind me asking what kind of setup did you have for your custom turbo?

 

it was a t4 garret turbo, custom fabricated exhaust manifold, tial 44mm wastegate,tial bov, with interceptor-x

 

also cat deletion with racing beat exhaust system

 

i would atleast have him take all the custom parts out and install the oem stuff. that's the least he can do. then atleast the dealer can replace the engine under warranty.

 

its to late for that, i had the car towed to the dealer for a compression test because the car did start even though it took awhile to get her going only to find out from the dealer that the compression test was so low that it wouldn't register

 

i know now one rotor and one housing has to get replaced

 

If they are tuning your car with a AFR of 18, maybe you should take it elsewhere.

 

Yep, sounds like inexperienced tuners....

 

yeah, how did it get to 18 AFR?

 

Very sorry to hear about your misfortune. Sounds like the project was going well.

 

how the hell did they get it to 18? Did they do that on purpose? Who's footing the bill?

Stock, your car will cut the fuel completely if your AFR is too lean. I guess the interceptor-x bypasses that protection.

 

They seriously had to have altered the fuel quite a bit, because it comes pretty rich from Scott, as a safety measure.

 

Eventhough the original poster will probably provide the actual explanation.... im guessing there must have been a failure with the fuel delivery system. Like no fuel.

-hS

 

We need the full story. We have many interested people here. How many pulls had he done? What AFR did you start with? Why was he so lean? What boost were you running? How long was the Interceptor on your car for before tuning?

 

Wow...18...they must not know what they are doing, or couldn't figure out how to use the Interceptor...yes, more details would be appreciated...

 

first off all i would like to say that i bought the interceptor-x because i heard a lot of good feedback from members that bought it and i know that its not the problem at all. first of all the tech at the performance shop here in illinois that installed the turbo and tuned my 8 which i was under the impression he understood everything ran it extremely lean. i paid for an upgraded fuel pump which turns out a month later he did not install. i cant reveal to much because ill be taking this guy to court to settle the damages caused on my car.

 

the first dyno run produced 174.2 hp and the second dyno produced 161.7hp at both air fuel peaking at 18 i have the dyno sheet to prove.

 

I have a brand new renesisi engine for sale. If anyone is interested, my email is wwkicker @yahoo.com.

 

i had my car shipped to mazsport scott for engine rebuild and where he will properly tune the car with his interceptor-x. will let you know how the progress goes

 

tuner sounded like a douche

 

Post some pics once Scott cracks it open - would be curious to see the guts.

 

Definitely sounds like your tuner didn't know what to do. After one run at 18 AFR he should not have taken a second without drastically changing the settings.

Here's what most tuners will do:
1. Run a baseline pull to see what the car does with boost controller turned off.
2. Verify/adjust for proper AFR/timing with boost controller turned off.
3. Increase boost by ~2psi and repeat Step 2.
4. Continue until target boost level is met.

Joon, would be really cool if you brought out your 8 to one of our Chicago meets once Scott gets it up and running...good luck with the car and please keep us posted...

 

red devil sure once i get my 8 back hopefully by the end of this month. what area in chicago are you from?
