The Stock Engine Thread

Hi all,

I'm wondering if it's possible for all the FI owners to chime in with their experience/results so far on the stock engine. Yes, yes, it's well-known by now that under 300whp on pump is somewhat safe and low-to-mid 300's is possible for ethanol etc.

But, it would be nice to have a compilation of individual experiences.

Please kindly answer the following questions if you are on the stock block. Thank you.


How many miles since FI setup:
Type/Brand of FI (supercharged or turbo):
Torque and WHP:
Fuel Type:
Vehicle Use: Example: 90%-5%-5% [That is, 90% daily, 5% autocross, 5% track days]

So 15psi and it blew on e85 of course, right? not some mix or 91/93 stuff.

I just gotta say this is impressive, 360 whp track use (so not babied) is awesome!

What would be the main factors? E85, oil cooler and a good tune I'm guessing? What more can be done to make sure the engine lasts..

I think he should probably clarify what map he is using on the track. Most people run more aggressive maps on the street and more conservative maps on the track for multiple reasons including things like longevity. I wouldn’t assume his peak numbers are what he is using or sustaining through his events.

Good tune, proper cooling.

I use a variety of calibrations on track, depending on the nature of the event I am at, but the full power map is frequently used, in temps as high as 115F ambient.

What other cooling can i put on? I got oil cooling, and the intercooler that came with the kit and fans.
