interesting!!

 

30+psi yes, kaboom no. What are the turbo rated to flow each?

 

(J correct me if i am wrong)

i think he is using the regular aps tt kit so its a gt25 turbo, so id say they flow to 270-300hp each


(not sure if this is the right gt25r chart)

 

Ok, your corrected..

APS extreme...More like twin GT30's.

 

^^^
oh its the extreme kit, awsome! (is this Zonis car or yours?)


i guess its like about ~ 430-450hp each then

 

Mine.. Zoni's. Vinos..ect....

 

Now that would make this thread interesting.

At 30-32psi it's still 72% efficient. At best you got 100lbs/min which we'll yield you about 850rwhp. That would be 142rwhp a cylinder, which any decent connecting rod will take without breaking a sweat.

Surely you didn't install stock rods in your newly built knife edged crank engine so all should be good.

Big valve ported heads, built bottom end, supersizeego, I mean cams with some black magic voodoo MRC tuning on a Dyno Dynamics has got youtube written all over it!

 

Nice. If these cams were available for my build, I would have gladly used them.
Nice work. What size are the stage 3 cams 284's or something?
I think the Stage 2's were 272's right?

 

whenever i eventually do the cams, these will be the ones I go with.

 

Nice comparison Julian.. these cams will be a part of my build

 

Videos of idle and reving..

 

Damn that sounds good. How much are these cams?

 

Last time I checked about $1100 range..Or so..Give me a shout tommorow, ill check pricing and stock.

 

Do you think these cams will pull to 8k rpms?

 

The Stage 2 cams are 264 duration and these Stage 3 cams are 272.

 

Very interesting results and not what I was expecting to see! I expected to see substantial high end gains, but I'm surprised to see the power coming on sooner with such huge midrange gains. I thought that bigger cams typically push the powerband to the right?

Looking forward to a 14 PSI vs. 14 PSI comparison.

 

Ill be the first to know, you guys will be the 2nd..

 

Well the larger cam with the larger turbos, are allowing them to breath a bit better..Im thinking the lift is not the big factor as much as the duration...Were also not disregarding the fact that we had the crank knife edged, but I dont think that would make 70 ft lbs. itself...

 

nice results. looking forward to the limit pusher tests (8K RPMs). Also liking that growl!!!

 

Me too....Does it not sound like a V8??
