i'll take the xf throttle body. please email me your bank details and price including postage and i will send it tonight. [email protected] Thanks, Ariel

Hi Manoj, Can you please call me regarding the cams. I have had no luck trying to contact you for the past two weeks !! Thanks, Ariel

check out fullboost dvd 2 and you see logs of it revving to 11+......when you get a chance to see the log, maybe you can understand why it didnt last too long finally...

are you selling the sandwich plate which sits between the head & throttle bodies ?

you will find that a radiussed bellmouth sitting on your base is the best for flow, which is the main reason why people go for a different plenum. greedy 2jz, jun sr20 & maybe greedy rb26 all have raised bellmouths

- Timing cover can be in any condition as long as it is all in one pice - Sandwich plate - the part that sits between the head and throttle bodies. Mate needs it to complete his conversion. Happy to pay for postage from anywhere. Im in Wollongong, NSW 2500. Thanks, Ariel

air pressure is one thing and air flow is another. although air pressure can be constant between cylidners the air flow is not. it is affected by a large number of factors, but as mentioned before, the less bends the better. aerodynamicswithin the plenum play a major factor and not something that can be shown on a flow bench, but more on autocad style programs which simulate different circumstances of air flow/pressure. all this and then throw in air speed and plenum volumes and the fun begins...... more pressure = more airflow (in general*) more air flow = more power (with the right amount of fuel of course) then again you can have more airflow @ less pressure (due to less restriction) = more power...and this is what a correctly designed and fabricated plenum should provide. * more pressure can sometimes produce the same amount of air flow at a lesser pressure since an orifice can only flow a certain amount of air regardless of pressure. basically, at some point the air "banks up" and can not get thru

he supplies all of my aluminium, from sheet to custom made bellmouths and runners thats right...to buy

or try jnt performance on 4257 1000 and they are approx $300 each

was it sold ?

what lift are the cams ?

maybe something like those in the sig ???

as always thanks Ben. same plenum as seen on Spool Imports car in recent Zoom magazine...T04Z making boost by approx 2500rpm

depends what greedy you go for. i was supposed to have someone send me one to flow test but it didn't turn up. mine are $900 + delivery and i need a set of runners to do it.

a 4% variance on mine compared to 8% standard should help eliminate that problem totally agree 100% nismoid...but boost is not always best especially on older engines like the majority of people have...the extra $$$'s spent could save you a lot more in the future. not only save the pistons/rings from detonation due to poor air distribution but also wear and tear, but i think we will agree to disagree

you are both missing the point......EFFICIENCY.......therefore making the power easier (less boost) and with most probably other benefits like increased torque and throttle response 4 figures and you are getting ripped

....and the yanks run 1000+rwhp with a standard gtr plenum....doesnt mean its any good (note i am not saying it is/isn't) one thing you are forgetting is efficiency which is the true indication of a well put together combination. this is missing in a lot of combinations which are neither here nor there in terms of overall performance and could be a lot better its not what you do but how you do it...remember that

how about the sandwich plate between the head and butterflies...is it available..if so how much ? Ariel

sold - please delete

yes bench tested standard plenum avg per runner is 265cfm, my one 290cfm. standard max variance between runners of standard is 14%, mine is 5% using standard runners. as always, thanks ben yes they have bellmouths on the inside..no decent plenum shouldn't mainly after rb26 head performances parts or trust style oil pump

willing to swap for parts of interest...pm me

As the title reads and the pics show. Customer no longer proceeding. Usual price is $1,450 + delivery Plenum $900 - 80mm tb $400 - Polishing $150 Best offer over $1000. This is a one-off. Will fit VL Commodore, R31-R33 Skylines with r33 rb25 head Ariel Ph: 0403 279 000

80mm $470 or $570 100mm with tps and tps plug which can be wired into rb harness come complete with weld on adaptor

unfortunately not, but if anyone has one, please send free to send it to me, i will pay for postage there and back (even a chinise copy one to compare the two) so i can test them on the same bench i have tested all the others. just like a dyno, this is the best way to get consistent figures.
