East Coast Supercharging just broke 500 RWHP with the new TFS heads and their custom cam. Rumor has it they said these are the best heads they have ever tested, they bought them directly from TFS. Pretty impressive with STOCK EXHAUST, through the CATS and WITHOUT flycutting pistons!!

Impressive Numbers thru Stock Exhaust & Thanks for the link .

peace

 

And Cats!

 

wow-congrats, over 500rwhp is insane on a stock size shortblock.

 

What does that mean? Milled 225's ?

 

i cant go to that forum, i have been lifetime banned, someone cut and paste the info into this thread. im running stock exhaust on my 403, was this all motor?

 

Just finished our newest head and cam package after a few months of R&D work. We have been working with Trick Flow to get a head exactly to what we have been looking for to match our cam. We have been through a few cams to finally come up with this package. The best thing about it is the combination of drivability and power. We feel we have come up with a very good package that makes great power and has very nice street manors. We will be getting a video up to display the idle as well as the drivibility. Here are some specs on the car..

2001 Z06
ECS Trick Flow heads
Custom ground ECS cam
Double roller timing chain
American Racing 1 3/4 headers with high flow cats
Fast 90mm Intake
LS2 90mm Throttle body
Vararam air intake

The best part is this was done through the cats with the stock titanium exhaust still in place.

 

It means some material was removed from the heads to increase compression and the 225 stands for the runner volume.

 

No, I think he's asking what makes those heads non-standard TFS heads.

 

those are some really impressive numbers with a stock block.

 

Right.

 

They are the 215 heads, I know they were milled, if you want to insure you are running their exact head then buy it from them.

 

I couldn't look at the dyno graph because I'm not a member on that site, would some one mind posting it in this thread? Thanks in advance

^^^ Your welcome.

 

^^ Still 400 TQ at 6500 RPM. Looks like those heads flow like crazy.

Not to mention the power is practically still rising when he takes his foot off the gas at 7k.

 

Look again. The combination includes American Racing Headers with stock titanium muffler system.

 

Is the Fast Intake out of the box or ported ?

Omg !!

 

The heads were decked and cleaned up by ECS.

Yes it AR headers with cats and a stock Z06 Ti set up.

The fast 90 was out of the box, and bolted on.

They are finishing up a cam only car right now... and the numbers should be out tomorrow.
