***EDIT***

 

The pulls were done in 4th gear (1:1), and the corresponding engine rpms are as follows:

80mph = 3870rpm

90mph = 4340rpm

100mph = 4850rpm

110mph = 5320rpm

120mph = 5790rpm

130mph = 6300rpm

140mph = 6770rpm

150mph = 7230rpm

160mph = 7750rpm

 

***EDIT***

 

...the first graph was the best pull - the second shows a very similar pull that continued to 7600rpm (I quit too early on the first one).

 

The last pic is a comparison to my last trip to the dyno about a year and a half ago - blue=old red=new

The main difference today was the elgin cam vs the very mild Isky cam that I was using before.

 

The ignition pickup for the Dynojet was a little flaky today, which is what was causing the spikes in the torque reading - It appears that the torque was maxxing out at about 470 lb-ft or so.

 

Sorry if I sounded too cocky - I'm just pretty pumped by the results. :D:D:D:D:D

Here are a couple of pics, I should be able to dig up more if anybody wants to see them.

BTW, since these pics were taken, I have given up on the electric water pump and electric fan - today's pulls were done with the good old-fashioned stock mechanical pump and viscous-coupled fan.

Where did you get that great looking header? Or who made it? Those are great Numbers!!

Ahhhh... the South Florida Performance header. Brings back many memories. The final product ended up quite good, but there were many many frustrating moments in the buildup of that piece. If you were to take your car to them and leave it, they could probably do a decent job, but I would not recommend trying to have them make you one any other way, unfortunately (actually, I seriously doubt that they would be interested in making any more, anyway). Joel can probably fill you in on some of the horror stories, too...

I would not recommend doing business on any level with SFP. The header I bought from them was garbage from the get go and they never would make it right. Ended up getting a $1000 store credit after going round and round with frank a few times and him refusing to give me a refund on it. They are such a hassle to deal with that I still haven't redeemed all of my credit.

 

Sorry for the rant.
