how much boost were you running on the IPP stage 1 block? This was the full longblock correct?

 

Have you been in contact with IPP to give them a heads up on the situation, and get their thoughts?

 

Tuned at 12 PSI on a FCon, I was running a IPP Stage 1 short block on stock heads. My power goal was mid to high 400's WHP, so there no need touch the heads since that can support those numbers.

Yea, Kyle is the one who send me the pictures, and the verdict.

 

so what was ur actual horsepower and torque numbers? and on what kind of dyno cause that seems weak for the motor to crap out, who tuned the car?

and they are not going to help you out with this? how long has the motor been in the car?

 

My actual WHP was weak. 410 WHP @ 12PSI on Forged Performance's Dyno Dynamics tuned all day by Sharif. I don't know about TQ because the part of the dyno that measured TQ was broken when my car was tuned. The motor was in the car just under 5000 miles.

 

I've spoken to citymonkey about this already, but haven't spoken to Kyle yet. From my experience, detonation is fair more likely to damage pistons and rings rather than pound out the bearings.

I really dont' like these situations for anyone. Kyle is good engine builder and I've tuned probably close to 500+ VQ35's and this particular engine was really super simple and safe. Stock heads, 12psi, and very moderate power. This isn't a tuning issue, but more than likely some kind of injector or airflow imbalance. It's just very peculiar to have 1 cylinder with these symptoms.

 

why did it make so little power though? or is that the normal for that setup on that dyno? that sucks and i hope IPP comes through with some real good support.

 

Terrible situation to be caught up in...Builder will blame tuner and Tuner will blame builder. It will never end. TOTAL FAIL!
Best bet would have been to surrender the carnage to an unbiased third party. But even those results can also FAIL. Too late now. Sorry for your loss.

Good Luck rebuilding. Hope you have deep pockets.

 

It's a little on the low side, and has also been discussed with citymonkey. I would expect about 450-460whp@12psi with stock heads on our dyno. Add about 10-15% to replicate a typical DynoJet number.

 

yeah that sounds about right...Is there any thoughts on why it didnt make the power? The power it was at ive seen many stock block cars take for years

 

How do the heads/valves look? In for injector test results and a look at the plugs..

 

I was told I made not as much power was due to my 2.25" test pipes and 2.25" HKS exhaust. I upgraded to AAM 3" downpipes with open wastegate dumps and AAM 3" exhaust, and was going to put it after the rebuild.

 

Without a retune, wouldn't that upgrade lean out your boost maps?

 

A re-tune was part of the paln.

 

It wasn't clear in your post, but were you running with the 3" components or not?

 

What is pictured above is clearly detonation. Its cause, I'm sure, remains to be seen. But, I wouldn't say that it was airflow issues unless there was a problem with the runners of the intake. Better chance of winning the lottery than this. If not tuning, then definitely a faulty injector. Was this car tuned using a knock amp?

 

At the time of the motor failing no. I just sold my HKS this month.

I don't think is the runners, I have a MREV2, and we all know about Tony's work. I going to ship the injectors to get tested soon, and yes I have a knock amp, along with dual wideband A/F's sensors.

 

Fuel Injector Shop in Florida that I used once before contact Yen 561-427-0082.

 

Did you notice any changes in A/F ratios recently? Have you checked to make sure the knock-amp is installed properly? That level of detonation should have been seen by the knock-amp.

 

what's your plan for a motor now? get another built one? find a stocker from a junk yard?
