This has to be fake. Ls is the best thing that ever happened to car world and especially 944. The only thing that one can do do make 944 drivable at all is V8.

Surely you meant Beavis and Butthead? Or Dumb & Dumber?

Butt dyno is very deceiving, traps speeds never lie....

Roasting this guy for all the crap he's spewed would need all the fire on the west coast.
I haven't seen you post this much since your build.

I'm bored.

Hoping one of these guys will bite on trying to top my trap speed.

Honestly the car is running so nice and reliably, that there isn't much to report.

i don't have LS7 valve guides.

I'm running ported LS3 heads.

so the night before last - I drove from LA to the Phoenix area....

overall, the 380 miles was dull and uneventful.

it was a hot night though with the desert temps ranging from 84 to as high as 92F in the late/wee hours.

the car seems to have been running a bit warmer than ideal. in any case,

during the majority of the trip, i ran a wide range of RPM's.... between 2300 and 2600 (78-86mph).

with the occasional 3000~3200 rpm yawn (98-105mph)

yeah, sometimes you gotta say what the heck....

live on the edge.

this morning i woke up to 70F in the suburbs of Phoenix.

car ran in the middle of the temp gauge on the morning commute.

having driven the car about 800 miles during the past week, and mostly during southern California's recent extreme heat wave,

it's fairly clear i'll need to run a fan behind the oil cooler.

space is tight.

we'll see what we can do.

Check the fan shroud for air leaks to the radiator. Also the ac condenser should have a shroud behind it direction the air to go thru the radiator. And the temp neddle may be off. I used open cell door jam foam strips for sealing the shrouds, works great. Good to see your not using the LS7 heads with the valve guide issues.

thanks.

Doug pointed out that I have a significant gap of several inches between the rear of the lower front valence and the front of the radiator.

so air probably isn't taking direct path to cool it. i'll see about closing the gap.

not sure if serious. I think you like roasting me much more bettah.

1. car runs real, real seriously good since the visit to the tuner.

2. any lack of power is either only remotely noticeable or not at all with spirited driving.

3. power delivery is just about perfect when you give it a lot of throttle through the low gears.

4. I drive a lot in 5th at 50-65mph, say like, driving on Coast Highway or in heavy traffic on the interstate, etc....
then, when you pop it into 4th, the car launches violently.

5. so, in 6th from 65-80 mph - when you drop into 5th, the car launches really, really good.
redline in 5th is like, 165~170. obviously, the dyno suggests it is going to dog out a bit after 4500 rpm....

still, with everything already so far past awesome, i'm not sure I care.

with the stingy, oem pump is there any upside??

besides less likelihood of driveline issues....

how 'bout less of a chance of fire?

since the fuel supply is on the stingy side, is there any chance this condition will allow for better fuel economy?

Allen, order the fuel pump already.

The last thing you want to mess with is your AFR Map. Trust me.

So you are not supposed to alter the A/f ratio? where did you learned all this stuff?, 911 guys are amazing, you need to tell all these 951 fans about your findings, they like to play with their AFR all the time.
