Mark VIII on a dyno

(Click here to view the original thread with full colors/images)

Posted by: driller

I was at a car show last weekend and put the Blue Flame on the dyno to see what it would do. I'll have to scan the chart but here's a video clip:

278.1 RWHP

Disclaimer: This is not a dynojet.

I had 2 pulls, the second put down 259.5 RWHP, but the converter unlocked when I went WOT and then locked back in.

Did I see smoke coming out from under the car? Maybe its normal IDK

If you couldn't tell by the sound, JP was running his cutouts and scaring all the little kids.

278.1 ..... Nice number NA.

VERY good numbers JP!!

you should have done one with cut outs open and closed to see hp differences

Yeah, it's normal. I suspect the old girl has some blowby.

Been there, done that. It's tough to get 2 identical pulls without being able to hold the tranny in 3rd with the converter locked.

id be scared to run it so hard at such a angle, all the oil at the front of the pan not at the back where it should be

Posted by: crownvicjim

I was thinking of the same thing as chicken. That's a heck of an angle to run it at...

Well considering the low oil sensor is towards the rear of the pan and the low oil level warning never came on - I ain't skeered!

Again, I'd have to scan the graph but the rpm numbers were skewed low since his pickup wouldn't read good through the extra covering on the LiveWires spark plug wires. Redline by the tach was around 6500 rpms.

I wouldn't necessarily take these numbers to the bank, but it was representative none the less. Other cars on the dyno that day seemed to put down reasonable HP for their setup.

how much do the exhaust cutouts help? ive considered putting some in mine for when im at the track but ive heard mixed things about back pressure

Posted by: driller

Testing at the track yields a consistantly better ET by at least a tenth with the cutouts open.

Posted by: slowmkviii

are your cutouts power ones if so have you ever tryed to open the 60 ft or so down the track

Yes they are electric. I also have a cool controller which has an external ground trigger wire. I plan to eventually wire up a timer switch to a WOT switch. Then all I need to do at the track is just mat it off the line and everything else will be automatic. I can adjust the timer to delay the opening for best results. In theory that should yield better short times and still give better top end HP, but without actually being able to trigger the cutouts at precisely the same time it is impossible to test the theory at the track.

Nice numbers
I get a kick watching the ten spokes spin one way then the other way then be still then spin fast.

What the heck did you do to pick up 20 ponies? I think I missed something. Can never keep up with you
