Procharger Stage 1 Kit is a huge disappointment!

[DiabloStang]

6.5 PSI is spot on for a stage 1 HO kit ( assuming you have a 4.38" pulley). I went through this myself wondering why I wasn't hitting the estimated boost numbers I was told the kit would do. At the end of the day, they are just estimates and there are several other things to take into account. I hit 6.5 PSI on a 4.38, then I pullied down to a 4.10 and saw 7.6 PSI. I just ordered a 3.85 and am hoping to see 9-10. What did Procharger say when you spoke with them?

Did you update your injectors?

Update. I brought my car to Cal Speed in Bakersfield to get dyno numbers and possibility a better tune. The guy was really busy, had coyote swaps everywhere so I felt pretty comfortable he knew what he was doing. He had a Dynojet installed outside and was using HP tuners to run the numbers and adjust the tune. The car initial put down 595 whp at 7 psi of boost. He was able to squeeze out a few more hp’s with a final pull of 631 whp. Now 631 hp at the wheel seems way to high for a stock stage 1 procharger kit. I honest think that was the HP tuner software calculating flywheel hp. I got a sketchy pdf dyno chart, it didn’t even have torque numbers. I’ve emailed him multiply time to get a normal Hp and Torque graphs but haven’t heard back. The guy is crazy busy and the tune was dirt cheap ($300) so I can understand why he could have possibly over looked my emails. Overall it was a good experience. The updated tune is much smoother and according Cal Speed my box tune from procharger had the fuel trim maxed out so I’m glad I went.

Could some with experience in tuning with HP tuner comment on whether or not this is calculated flywheel or actual whp?

Yes, I didn’t want to take any chances. ID1000’s and a BAP

That looks like a 3rd gear pull given the 125mph peak.

It was 5th gear pull. It has 3.73 with a slightly bigger tire setup in the back. Also, I wouldn’t count on the mph scale being correct considering how shitty this graph is. I’m not sure if the gear pull would even matter with hp numbers. Torque def but in this case I don’t have it.

Strange looking chart for 5th gear. Hell weird lookin chart period. Never seen one like that before.

Agreed. Like I said, it’s def sketchy. I do remember watching him then asking him what gear he was in. He confirmed fifth gear idk.

If it was me in your position. I’d find a drag strip. And see what the car does. That way you have more data to throw into the equation. You can tell a lot from a time slip.

You probably installed it backwards. And it’s sucking all the power out of the engine. Instead of blowing air into the engine.

Hahaha thank you for that

Agreed, need a slip for real world validation.

If you are an auto car, and changed gears and tire size.... (which it looks like you have)

There is a LOT in the tune that would have needed to be changed to deal with those.
Otherwise, you will have lots of TQ issues out on the street as the TCS and trans won't place nice.
Sadly thats something that would have to be addressed with a custom tune (which it looks like you have)

On our EO systems, they are designed for 100% stock cars (other than exhaust)
They make the same power as our other systems psi for psi.
Depending on fuel quality can range from 580-660 rwhp.

Really!!,i have made several tire size changes with my car and never have to make any adjustments.The output shaft speed sensor takes care of this and learns as long as its not a huge swing in gear ratio.I personally think he expects too much for just 6.5 pounds of boost,but could be wrong.Its hard to compare boost on these cars because so many things effect it.

Gear change isn't the end of the world. But gear + tire change, can = issues.
Especially if the front to rear ratio isn't the same, or brands change.

TQ calculations can be thrown off, then MPH vs OSS can be thrown off. (they will fight each other)
The TCS system isn't super excited about it either.


6.5psi with 3.73's should = total tire destruction...at basically anything below interstate speeds.

 

[BlueCollarDaily]

Maybe I'm missing something but the 83lbs/min MAF should be 800 flywheel? But he cant feel it pulling? With 3.73s what gives ?
