wow, ray wilson built and tuned bridge ported t78
 

here are the runs at 15 psi and 10 psi. thanks ray:)
i am selling my front mount greddy two row. make offers. I took my car to summitt point (shenandoh course) for my very first track and had a blast. I was a pussy and ran it at 10 psi.....but i turned up the boost to 15 for the last session. i will try to post a vid soon. kvn

wheels are for sale too. props to s2ki forum members for letting me use their motor home and tips. kvn

full bridge or half?

damn nice numbers. Now you need to either get some c16 or alky injection and turn the boost up!

Damn I'm more impressed with your numbers at 10psi more than anything. That power band is very nice.

Great Numbers, Love the Wheels. Blitz?

nice fd

seriously, 400rwhp@10psi on the greddy t78 is flippin great!

Full bridge. And congrats Kevin!

thanks ernie, now i need 400rwhp more to have what you have. lol kvn

found an action shot on s2ki

Is Ray making these kind of numbers on other shop built motors or just his? I have scene many great looking dyno sheets from him but they are all hisa builds. Wondering if he will be able to this on others. Not knocking him but wondering if he has it down packed for a certain port job/timing map he is running..?? I could be way off here but I have been wanting to take my car to him..

I like your numbers and again congrats ;) that woluld feel very quick !!!

On topic of if bridging is worth it, i honestly do not know? i will figure out how to post up my autronic data log to back up my dyno that i will also post for you to compare but in summary this is it.

At 7500rpm i made 472+rwhp on a peak boost of 19psi v's your 17.5 (peak tq) and 17psi v's your 15.6 (peak power) (map ploted on ECU loging), 40 deg C air temp after IC on pump fuel with TO4S turbo (58mm comp wheel) smaller turbine wheel (P trim) than T78 greddy and on a street port and this was done on a dynapack chassis dyno which is accepted to give lower reading than the dyno jet *my boost is also run at 610m above sea level, so at lower altitude could use less to obtain same power*

I did two runs back to back on same graph that were within 1.5% of each other in power and tq.

I only share this with everyone because it seems very much that to me the bridging be it partial or full is not realy worth it at all in power terms? it will give some more range in rpm it seems but little else?

If somebody else builds the engine, the clearances, and porting, materials used will all be different. So if the power is less, this would be why. Kinda self explanitory.

Rice, I have to disagree. Ray has done about 7-10 bridgeports now. And the only thing that was changed was porting. Turbo, ems, etc...was all the same and they all have made an average of 60 more rwhp or more at the same boost level and the power band is dramatically broader.

makes sense, you realy have to compare an apple to an apple ;)

i love it made props. So your selling your front mount now what are you going with?

That's right about the same I've seen also. Now when you take it a litte further with a custom intake manifold and a turbo to suit high boost/power then the power is even greater.

i am thinking of a v-mount set-up so that the car won't get so damn hot during track days. the rad is completely blocked off by the fmic. kvn

ernie is right, all he did was change the ports. I did pick up close to 60+ rwhp across the board almost. kvn

unreal :)

I been fighting the urge to do this to my own car, but will have to give in I think :) :) :)

for sure something is setting Ray's product apart from the pack.... generally it is the totality of all the details lined up properly but perhaps a significant portion of the net is his BPs...

i can see a run on carbide burrs:)

hc

I could have sworn you where always advocating bridge ports???? Maybe I'm just confused.

200hp by 4200rpm

Nice :)

Just so people know Ray uses STD dyno numbers. That is about 15-20 RWHP more than an SAE number. Its still a good number but inflated a little. Most shops use SAE.
