im so glad to compare mine to yours, its good to see i didnt loose torque or low-end power like i thought i did with my RBC... and yes, i cant wait for my results after my build!!
I have overlaid mine and EUR003ACT dynos. Same dyno as we know, very different mods. I did this by hand but is very close. Im doing this analysis to determine the best mod for me next. I prefer to deal in facts than approximations and seat of the old butt. This as as close a dyno result you can get, Similar cars, similar temps, same dyno, same configuration on dyno:
Interpretation. I have less mods and a lower quality header. I do have the Jtune mild with a 5000rpm vtec.
Seems to me that my earlier vtec and tune allows me to equal a more modded car from 5000rpm. But once we hit 6000rpm and Justins car hit vtec his better mods + RBC allow him to pull away quite a bit.
Idont understand my lower torque at the start as my car is pretty torquey in normal driving, much more than it was stock. And given i have the RBB stock Intake manifold, which is supposed to be torquier then the RBC that Justin has at lower/mid rpm, it doesnt make any sense to me except to say his current mods have really worked down low for him regardless of his RBC. I do pull away in torque and power at about 3500rpm to about 5000rpm. Thats the RBB intake manifold and my jtune Im thinking helping mid range torque. But when justins car gets a gob full of air from the RBC + mods at 6000rpm it really takes off. Better breathing mods no doubt.
What do you guys make of this?

I went to the modded XR5 Turbo with Mods - the dark side.....BOOOOST!
I dunno if a RBC + Larger TB is going to net me 15kw though. Maybe 8-10kw at best. Then you got pulleys and a much better header making up the extra 7kw which is very feasible and realsitic i should think.
I think my Jtune reflash might like the RBC a lot though given the A/F ratios. Heaps of room to increase the air going in and keeping things safe i reckon.
Cant wait for your new head and camshaft. Thats when the rubber will hit the road, or should i say your dollar hit the killawatt!

Sweet. i will fix it but for now I will enjoy the nervousness that justin is feeling having his baby posted on TeH InTaWeb with 20kw missing..NOOOOOO
How do you reckon a mainline Dyno compares to a Dyno dynamics? Im seeing some bascially unmodded cars above nt his page going higher than mine on these other dynos? Makes me wonder what Justins would do on a dynodynamics. But is a moot point i guess and for pissing comps only.

he just wanted to beat you justin.
nice overlay suntzu.
hahaha its a conspiracy! lol atleast when i do the head build ill get better gains tho hahaha
and yes rus i agree with ur assumption on where i get the power... 8-10from toda headers/metal cat/ur pulleys... and 5-7from RBC
for all you interested parties (eurojazz08 / russell) i just purchased another J32A3 throttle body and RBC intake maniold... ill be modding them to mate with K24A3 and porting out to 66mm...

hell yeah thats my thinking too!! i reckon ill get more off dynodynamics... i think the mainline one reads VERY conservatively...
wow man 113kw? suxs dude for all that money and time your putting into it, i reckon i could take you with my stock despite your fancy RBC and assortment of mods . PLEASE GUYS a 0-100 time at least! the mods look great but i want to know what they are capable of on the road!

Ive seen some wild variations in Dyno Dynamics as well, something small as not using the air temp probe on the DD dyno's can rob you of 10 - 15 rw/fwkw....
Dyno's should be used as a tuning tool, and what you guys are doing is spot on, using the same dyno, hopefully with the same operator, and just analysing different mods and what difference they can make, power output wise.
Shootout mode is what you need. Then you can compare to all the other cars that run on that day. Time for you to make a trip to Sydney for a dynoday on the Dyno Dynamics. LOL
here ya go buddy, found it for you
