after building/porting the motor i asked colin if he woudl go to the dyno after the break-in was complete, i was curios to see what the stage1 6 port street port i have created would put down. i consider this stage 1 because it is the largest i would go on something where a steady idle at aroudn 1k rpm is required and where no significant changes in the way the car behaves are made, from a stock port motor. noise is kept to a minimum and streetabilty remained. there was nothign to tune the car with at the time, so this was just a baseline to see how the car is runing. colins next purchase toward controling the engine is a microtech standalone unit after which i am assuming we will hit up the dyno yet again and see what diffrences are made by tuning the car in better. this car was very lean at some points on the dyno and it would be nice to have an afc to atlest dial the fuel in a little better. well enouf rambling take a peek



there is an update to this thread

relevant mods:

s4 stock ecu no piggybacks, stock ignition timing

s5 rotors and counterweights

t2 exhaust inserts (rotor housing)

t2 intake manifolds(this didnt seem to affect power, except its like having the 6 port sleeves removed on the NA manifolds)

stage 1 street port

racing beat catback

racing beat header

 

about howmuch bigger is the port than stock?

a good amount

 

Something is not right with your setup. I got 1 HP less then you with a ported 13B 4port with an IDA Weber down draft and... NO TURBO!!!

what turbo?

 

I just assumed that the turbo pictured in his signature line was part of the engine in question.

THERE IS NO SPOON! errr turbo

 

the car in question is not his. he builds/tunes cars. his sig are just pics of his work. by the way the car that does have the turbo you were referring to, is indeed slow.....

 

the pic with the turbo is an fd look at waterpump housing, not the fc he dynoed its a 6port na streetport
