I've been playing around with pulley sizes and I got some new graphs. It can get super hot after the intercooler with the small pullies. I don't think the 26psi pulley will see much action unless it is on the strip and I buy a power cooler. I never thought the temps were that high after the intercooler.
Temps at around 75 mph cruising were about 40° over ambient for the 17 psi, 50° over for the 22 psi, and 55° over for the 26 psi.
Notice that the air temp at the filter also rises as the truck accelerates. I guess even the 5" pipe which runs from the fog light hole to directly infront of the filter doesn't supply the amount of air needed to the 14" filter and the higher temps are caused by the filter sucking engine compartment air. I don't think that has much effect on the air temps after the intercooler though.

blue line is speed
red line is intake air after intercooler
green line is intake air at the filter

17psi

22psi

26psi-I never had this at WOT...

 

easter
nice work.....thanks Dale

PS...is this with or without the alky system working ??

 

That is with it. It doesn't lower the intake temps. It does lower the cylinder temps according to my EGT gauge. I have been told that if the spray tip was located after the supercharger and before the intercooler...???

 

Nice work, good to see someone doing real, usable, research.
Please excuse this non Ford owners input, but.

How do u like the way it feels when it's not warmed up yet? & then it kinda losses some power & responsevness, even more when it's hot out.

Well I have made a chiller that keeps the I.C. coolant pretty cool. 1 of the L's that I installed this on I measured a stock I.C. coolant temp of 110f on a high 70s temp day after I drove it up the moutain to my shop.
A week later the owner drove it back up here for insulaton to the system. Same outside temps & this time the coolant temp was 68f.
This is measured in the res. tank which is coolant that has just exited the I.C.
After the sys. was insulated the owner said he noticed another improvment in power & responce.

Every L. owner that has had 1 of these installed loves the improvement, 1 measured a never before obtained 20 MPG.



Interested?

20 MPG he must of been coasting downhill for a longtime.........

Lil bit more info on your "Chiller" would be nice........sounds interesting

 

Was wondering...........syclondave are you affilitated w/ the Guy who Usta Own the Black L on Naz w/ blue flames??????

 

I'll bite...

 

Easter, thanks for the data. How long were you into the run when you saw those temps ? What Im getting at is if you were only WOT for let say 5 seconds, the temps would be higher on a 1/4 mile run. I did similar tests on a my truck (Eaton with 6lb Pulley) I had a air intake temp of 84 degrees and at the end of test, air after the intercooler had a temp that of 134 degrees(50 degrees after increase). On a truck with a 4lb pulley he had air intake temp after the intercooler of only 114 degrees(30 degree increase) at the end of the test. My next 2 passes would be made running ice water thru the intercooler, I had 76 degree intake temps but at the end of the run my temps had only peaked to 96-97 degrees(I cant recall exact temp but only a 20 degree increase after intercooler) My cooler is made out of a 4 gallon fuel cell and is mounted in the bed. I dont run stock coolant through coils like other coolers do. I have replaced the stock tank with this cell, I use 10lbs of ice per run and after returning to the pits still have a water temp of 55 degrees. Before going to the staging lanes, I drain all but 1 gallon of water and fill with more ice. Im still having a problem with ice cubes clogging my inlet hose but Chicken wire should cure that. On the dyno, I made 17RWHP 25RWTQ on the same program. The cooler intake temps allow for more timing, had I added more timing into the equation, Im sure results would prolly have doubled. My current tune only has 17 degrees timing and I run a A/F ratio of 12:1.

 

It uses the AC for chilling the IC coolant.

The guy I know still owns a L like that.


Oh & I heard today that one of the other L's that has my chiller installed was testing @ the dyno Friday. They only got around 3 pulls in before the trans went away. But after 3 pulls which nomally raises the IAT to 160f to 180f, they measured a IAT of 50 f

& the HP #s went somthing like 430ish RWHP up to 470 something. That's the improvment the chiller made with some retuning to accomadate the 50f IAT.

There will be return to the dyno after the trans is fixed.

 

Those runs were just for a few seconds not 1/4th mile runs.
Problem with the ac chiller is that you will not be able to use it at the track.

 

Ok, hhmmm, do u know this from actual experiance or are u just assuming?









..........So then, I guess I should just disreguard the passes @ the track where my own truck & others showed only a increase of about 10f IC coolant temp after the pass. (with the compressor OFF)
And the other climbs up miles of a hill where the temp didn't rise.

And maybe you've seen a dyno pull that only lasted "few seconds" but if so it wasn't a complete one.
Most of the complete ones I've seen or been part of, last atleast 10 seconds.

 

The only people I know who run A/C at the track are the ricers. Usually they get thrown out after the condensation from the ac starts dripping all over the track. If you have a system which doesn't drip the condensation let us know.

 

Hey hey I use the A/C at the track, gets damn hot sometimes. You can thank me for getting water everywhere.

 

Never been a prob. here & 1 that is easy to fix.

So u don't have a real responce to your claims ?
