480HP/409TQ at Speed Inc today with a temp of 99Deg at dyno time. I'm happy

 

Congrats on some really great power, i bet it pulls hard. Do you have a graph you can post?

 

Wow thats impressive.

 

have a graph will have to work on getting it uploaded

 

Congrats .. A4 or M6 ?? either of them it still great numbers on SEB

 

Its an M6

 

nice numbers. im def considering these heads for my motor in the future. thanks for sharing

 

the 215 could be considered also. I went 227 since I have a wet nitrous kit sitting on the garage floor for it. Just need time to install

 

Glad to hear you are happy and thanks again!

 

I'm glad you're happy with your numbers! Looking forward to seeing that graph

 

Congratulations, great results !!

What's the compression? and are those numbers on a dynojet or Mustang dyno? SAE or STD?

Waiting for the graph

 

Congrats on the numbers! Makes me anxious to see what my results will be!

 

put a 12 bolt in it and drop 20hp. Do you 1/4mi race or just from a roll? Nice power.
SAMER-I believe he said speed inc dyno days so it's a dyno jet. if it were a mustang dyno he may of lost 15-20hp.

 

nice numbers stock bottom end

 

Very nice not bad at all...what head gasket and cc size?

 

62cc chambers and stock GM head gaskets. Having trouble getting the graph scanned

 

very nice Congrats..
Great work on tune Speedinc and great work on the package TSP..

 

Sweet numbers! The setup I'm putting together is very similar, just with a FAST 102/NW102 ported and 402 bottom end. Your results make me feel a lot more confident on the build. Why all the bashing from members saying rearend swap -20hp, dyno another -20hp, the temp was also 99* when it was done. Maybe that put the power down too? Give the man some respect and keep the BS out of his thread. Post up that graph dude!!

 

most dynos correct the numbers for the heat and a 12bolt will drop power. is it bs,no it happens..

 

Great numbers!!
