4.6L Stroker Dyno Results

[Gojeep]

mississippi_xj,

When I have time, I will put together a write up together on the specifics of how to wire in the Apexi. There is a show going up this week that I am a designer for and I wont have any time to do the right up. Look for an Apexi write up next week or the week after.

AARON

Excellent, I will look forward to that mate.

Indeed a write-up would be very nice and appreciated...
Got a 85% completed 4.7 stroker w/forged slugs in the basement that I'm considering adding an Eaton M90 to.

More engine monitoring data would be reeeeal nice.

:cheers: Good Job


p.s. RSALEMI.... been to the strokers group lately? I haven't, but thanks for all the tips in the past... Might actually finish the engine this year

That's an excellent thread. Any update on the write up?

Question: will the Apexi SAFCII work with OBDII XJ's with no O2 sensor. My stroker XJ is 99 and I have no O2 from the factory, same as Dr. Dyno.

UPDATE

Yes I did finally get around to doing the Apexi write up: http://www.naxja.org/forum/showthread.php?t=46515&highlight=Apexi

Yes, the Apexi should work with your XJ. The O2 sensor is not needed by the Apexi to function.

im just gonna average teh 3 stats till i scan the sheet

first 2 runs at 153hp, 203 tq
third run 150hp 200tq

AF was averaging right around 12.hi(89-99) above 2400
wish i had numbers below 2400
fuel fattened up the higher RPM.
just looking at it now-I bet my idle circuit is a little too lean.

tq started dropping off after about 4200 but was above 190 from 2750-up


pretty nice..

what this tells me is i have a little timing/spark issue, probably a cam timing issue or not aggressive enough cam and teh trans is a real power robber.

im getting enough fuel(maybe not being burnt correctly) but i think EFI will help me too.
