FTI/AFR/Edel RPM Upper Dyno Info

[final5-0]

There has been some talk lately of switching to the RPM upper from those who use the FTI/AFR/ performer upper combo.

A guy on the Corral 94-95 forum has a thread going showing his dyno pull using the RPM upper.

I thought some of you might want to see his results.

Are you learning anything up there at that institution ???

Interesting. Hard to draw much of a conclusion, I don't know what effect the tranny is having -- looks pretty soft on the bottom end, as expected. Does the auto tranny really suck down 30 ft-lbs of torque? Ouch!

I want to see a before/after for someone who already has numbers with a regular Performer intake, and I want to see someone try an RPM2

OH, plenty...

I have 18 credits this semester, so it's a little rough. I really just want to tune the car and go racing though. I think I'll be the slowest H/C/I guy on here if everyone keeps racing in these next few cold months.

His trans does kinda make it not so good of a comparison. I was having the same thoughts as you about the old slush box.

It's possible that his 3500 stall converter is throwing off the numbers. It's also possible that the RPM upper is sacrificing a good bit of torque for just a few more HP. People have made similar numbers, maybe even better, with the regular Performer or a Cobra intake. Of course, track times would paint a much better picture of the car's power.

Zenboy99 should be having before/after results with an RPM upper soon I think. He has a trickflow/FTI set up with a 5 spd. That is gonna be interesting. The automatic car makes it hard to compare.

Thats my graph...

I could only get the car to go 13.10@105 1.82 60'.
It was really hot and humid. A conditions calculator said its about .15 that day.

The converter is still a lil tight. We are going back on Wednesday to try some more stuff to see what it does.

Ed said thats enough power to go 12.40's

I have seen several combos that are similar but they all have t-5's.

Your hp curve is very close to mine and some of the others but the tq curve builds at a slower rate.

I don't know if you could feel the difference of the tq curves on the street or not but do you think your trans is what is causing the different looking tq curve?

I'm curious cause I really don't know very much about the auto trans.

Well if the converter is too tight, Its gonna be engaging to early causing the motor to pull its self up to the power band. Make sense? The cam isnt good til 3800rpm so the converter has to get the rpms up past that and I dont think its doing it.

I put my Performer RPM intake on this past weekend. Many stangnetters were very speculative and told me it was a waste, well from the SOTP meter, they were all wrong. The low-end power loss wasn't as much as everyone kept telling me about. The car feels exactly the same driving around the city, it maybe takes a little more gas to get it moving quickly from ~1700rpm. But man does it pull up top! The power doesn't drop off at 5500rpm like the Performer. Revving to 6500rpm on a stock short block is a little scary.

The local dyno days has been rescheduled so I don't have any numbers yet, but I will soon. I"m going to the Fun Ford Weekend in Illinois this weekend so the numbers will come sometime after that.

Bottom line is, I have a Performer upper intake for sale.

I'm glad to see you are getting things ironed out. Do you still have the regular intake? I'd be VERY interested and would bet the car would be a hair faster with the normal performer on there. If you were making peak power above 6000 and were shifting up around 6200+ I'd then think the RPM was the way to go. If nothing else, bump up your shift point next time out to 6200 and see what happens. Even though you are past your peak, you are still making good power as your graph doesn't drop off slightly. If you re-dyno it, I'd make some pulls to 6200 or so and see if it really drops off quick or not, this can also tell you if 6200 is too much, or possibly not enough.

I'll get a dyno of an RPM 2 up soon.. (but my combo is totally different, Ed cam though)..

Killer hit it on the nose. Went i first went out i was shifting at about 5,800rpm and was trapping 106.80s bumped the shifts up to 6,200rpm and was trapping 107.20-107.30.

When I shifted at 6100 I was trapping 105.9-106.2, I shifted at 5900 from 3-4 and trapped 107.1. I changed that because a few people on here said my 1/8 mile trap speed was alot faster then my 1/4 trap speed.

 

[94DreamGT]

Weird...I was consisting shifting at 6000-6100 and trapping 108.5mph+. I tried dropping it down to 5700-5800rpm and my MPH fell to 107.4.

I bumped it back up to 6200rpm and my last 3 runs were all at 108.9mph
