so i found an fd for sale it from florida, brand new engine from pettit, car has 118,000miles, all bolt-ons, idels weird like at 1,200rpm for $16,000 with all the original parts + a sound system ,car runs good ,boost patern is perfect ,starts up really fast, no power surge, pulls really strong 365 rwhp (data from the dyno graphs)

the owner has every receipt of every parts ,and services.

the car is black with tan leather


i think its a great buy!

Sounds like a Pettit built car. Most Pettit cars with full bolt-ons and decently sized ported motors pull around 350-360rwhp using their ECU's at 15 PSI.

If they are using a Pettit ECU without the airpump, that would be the reason the idle is higher. Unless you have a programmable ECU, when removing the airpump you have to raise the idle to keep it smooth. 1100-1200 rpms at idle is about the norm for that.

15 psi on a Pettit ECU is pretty dangerous (assuming stock injectors)....I popped my engine that way (multiple hard runs however)....they always told me 13 psi, 14 with race gas

It's not something I would recommend on a daily basis. We have to use our own common sense with some of this stuff.

Bluem

the boost is 12psi. and it running a power-fc

Unless it's got a single turbo, the current boost setting is not what was used on the dyno. Just want to make sure you don't think that 12 PSI on the stock twins is putting out 365rwhp.

Bluem

the dyno runs were at 15psi.

its set now at 12

Hmmm, i just dont see how this links to the thread title...

I would ask to see it idle at a lower RPM. An engine with a cracked apex seal can idle okay at 1200 RPM, but will idle like crap at 800 RPM.

the title is because i drove the car and i loved it ,

as far as the idle , it stays above 1000rpm and goes up to 1200-1300 and then it falls to 1000;
i think its a bad solenoid or loose vacume line ,because the 2nd turbo hits really hard but the car sounds and runs smooth.

im going to see the car again with my uncle , were going to doo a compression test , and i wanna check the vacume at idle
