I had a Wong chip in it, his custom tuning got another 10hp out of it and addressed some lean condition at higher revs, got consistently more power overall across the rev range, and addressed cold start and idle.
254 wheel on a dynojet with sae correction

How much/what is the Dynojet correction?

Spyerx

SAE correction. Most likely NOT much. As I live in SoCal, at sea level, it was mid 70's, maybe 10ft above sea level, maybe 40% humidity.

This is a standard here in US, as you know, near impossible to consider dyno to dyno. Dynojet is the most common dyno in the US, and used for sanctioned racing in most organizations, as the results can't be manipulated by the operator, and dyno to dyno the results are the same. Now, does 254 wheel compare to another brand? It will depend.

Another way to put it: on this dyno, with the mods I have, and the many, many cars Steve Wong has tuned, performed very well and as expected.

Regarding 300hp wheel with an ECU on this dyno configuration? Not sure about that, I think the intake, heads, injection will be limited. Based on known comparisons to engine dynos vs. dynojet, loss is about 12%, so that's about 289 crank. So I guess it's close with crank if that is what you meant.

Update: Just picked up the car. Wow, drives totally different. Super smooth idle, very linear and aggressive power delivery. Feels fantastic. Can't wait to rip it around the hills this weekend.

"meaning crank sorry"
Ah ok, not too far off from that now.

Did a few things this weekend:
--put over 500mi on the car the last 2 weeks, drove some canyons, it's FUN
--swapped all bulbs to LED - look good, less draw. I figured with the electric PS pump and the smallish battery less power draw is good thing
--Removed a bunch of unused relays and fuses from the fuse boxes, with stuff removed, no need
--I did the hot air cup-car mod for my airbox :-) Sounds awesome. And well, most use aggressive is moving, I don't drive in traffic or stop and go much
--Adjusted my gas pedal for better heel-toe action, have a rennline one on way, they are back ordered
--put some thin rubberized 'grip tape' on the driver side floor board, its nice. Won't destroy shoes like skateboard tape
--drove car very hard this weekend and well, I can confirm the secondary oil cooler works good.

Have a few to do:
--front end grip is massive, I may want to slow it down a bit, need time on track. either shock or sway bar adjustments
--I may want to dial in about 1mm more per side toe in, slow down the turn in and allow better control mid and corner exit. Toe out gives opposite, more aggressive turn in but less at mid/corner exit.
--I MAY have a bad brand new throw out bearing. UGH! When hot, in certain conditions, clutch press you can feel a slight knock. And, if I engage/release clutch several times it will go away. Shop is 95% sure it's the TOB. And yes, they've seen this happen before. FWIW, on my RS I had 2 brand new Porsche RS 4.0 pressure plates be defective. Its definitely not the engine, and definitely not the transmission.
--I need to check tires and tub/clearance. Front end is super tight, no rubbing I can hear, and no weird tire wear I can see, but need to get on a lift and make sure I'm clearances on the tires

During any pedal movement or when fully depressed?

Spyerx

Once it starts to engage and leverage/depress the TOB. There is no observable noise when the clutch is fully out. And it doesn't do it 100%, its like a certain loading condition causes it.

Seems rennline has a large back order on the pivot joints for the pedals for all models

More like a controlled slide. I think I have your PDF someplace on the original build. I think some things were nixed and others added. Looks awesome.

surely you jest. it's more like diving out plane with no parachute

I had his PDF list, that led me to sell my car.
I was scared.

^^^ You only live once might as well enjoy yourself while you can.

My track car has become one of those one way airplane rides. Although building this new engine is a lot of fun. It seems as though everyday there is always something new to add to the list.
