whats going on?

 

did you notice any difference with that apexi ws ? i sure didnt. please let me know.

thanks

 

yea this is wierd.. the gains cant be as crazy as anticipated if not one person has dynoed this

 

they have. and search is your friend.

 

There haven't been any good before/after dynos that I'm aware of.

 

i agree, none fully comprehensive, but there are a few, i can remember 3 off hand that had before and after numbers. plus the ones that Dave posts up for his test car.

there are dynos from i think one person but that dyno was open race exhaust, aftermarket crank pulley. I know for last year 10 people bought smsp headers on preludeonline and i have yet to see a dyno.. now there on their second run already

If the header is that impressive and i dynoed it and got 200 whp i would share that info!
There is a guy on prelude "DR" with dc cc header, aem intake, straight pipe, no PS, tuned air/fuel "not timing" that dynos 197 whp! i dynoed 179 whp with dc header, aem, msd ignition, vafc tuned, 2.5 car sound, apex ws exhaust.

 

I'll have a good before and after dyno as soon as I recieve mine which hopefully should be soon up against the dc header but it will also be with the carsound cat agains my stock cat

i really would like to see his dyno; those numbers are very high for those types of bolt on mods.

 

i will be doing a dyno with jun vavletrain and jun cams with a peice of **** DC header, then an after with a hytech stage 2 header we will see.

 

i just ordered my smsp , and i will prob dyno about 1 to 1 1/2 months from now
ill post em up

 

you have to go to preludeonline.com but you also have to pay to be a member.. i dont think its far off.. i know a couple of people including me dynoed 179-180 with vafc, he was telling me all i had to do is remove power steering and change my cat to straight pipe and apex n1 exhaust and i should gain around 190 whp which sounds around right

removing ps adds 1round 3-5 whp i think
going from car sound to straight you DO get gains still maybe 2 whp over the car sound.
and changing my exhaust from apex ws a chambered muffler to straight flow! im sure id gain more than 3 whp.
so thats 10 whp easy

thats why i wasnt really impressed with that smsp header becuase it doesnt show before and after only after with open race exhaust, crank pulley (no ps) etc..

but im not doing this on my prelude anymore becuase now i also have a civic track car so all my money is going to getting this car ready now
