Can anyone comment on the differences dyno'd using a Rev hard kit Stage 1 vs the JRSC street?

Also, I went to Rev Hards website and they show application of the stage one for the RSX Type S (which should also work for the JDM Type R I would assume), but do not show the stage 2 kit applicable. Anyone phathom why?

Also, something else interesting..the Stage one uses 440 cc injectors with 7 psi boost, but the Stage 2 uses the factory injectors (I think 310 or 330 cc) and the same boost. SO...how is that possible and get more power from stage 2?

Revhard has always made quality pieces and i expect the K series kit to be no less in quality as all thier B series kits have been. I don't like the Jaskson Racing kits for hondas but havn't had any experiance with the new K series.

Whenever ive read about the rev hard kit ive only read bad things.. motors blown, like stated above a car catching on fire and so on and so forth. I've heard good things about the jackson supercharger. The only bad things ive heard from it is that it shreads belts and sometimes the belt slips off... They might have made a better belt tensioner in recent kits but im not 100% positive. Lately all ive been reading up on is the comptech supercharger. So far its putting out descent numbers and an aftercooler is in development. I think the numbers for a 5psi pulley with stock injectors is 232hp and i believe somewhere inthe range of 160-70ft/lp tq. <----not sure of... Thats off of the k100 tune from hondata, if you used kpro and bigger injectors you would probably squeeze out another 20-30hp...

i have a ep3 with the revhard kit and 2 days after i had it installed i hit a 12.89 at 109 on slicks so if u ask me the kit is great
question for all of you guys, i just bought a si 2003, and i also plan to buy the rev hard kit, but the thing i want to know if why on the site revhard they claim 254 WHP and 228 LBS on that kit into the si?? and some of you tell only a + 75 hp soo that equal to 50 whp of more that it??? because the car is already in the 130-140 whp + 50 its only 200 -210 whp??! or its really 254 whp.

thanks

today i dynoed and at 7psi I laid down 249whp using 91octane and EMS. 10psi laid down 274whp with 100 octane...at the end 12psi 100 octane laid down 304whp 249tq but was dangerous since the fuel pump was maxed.

Installed Revhard kit at home and have had no problems at all. Runs strong and smooth.

I forgot to mention 2004 EP3 Civic Si
