TVSr1900 supercharger
upgraded fuel pumps
upgraded intercooling (vs. their basic $11,000 kit which went 11.8 @ 118)
upgraded coolant pump
LW wheels
Catless 3" downpipes
2.75" catback
no back seat
14 PSI I believe. They claimed a few months ago that it would be 15 PSI+ as if that’s a good thing lol.
IMPORTANT - AMD ran on a night when the Density Altitude was -700 to -850 feet at Pacific Raceways according to dragtimes.
JHM ran at +100 feet of Density Altitude when they went 126 and +200 feet when they went 11.34
A 1000 foot swing in Density Altitude is significant.
So to summarize the differences for BWT
JHM 8 PSI vs. Aviva 14 PSI - this is a huge difference of course
JHM 91 tune vs. Aviva 92 tune (negligible, buit a difference…and JHM had 93 in the tank anyway…however on the
JHM 93 tune this will get REALLY interesting. Haven’t bothered with race gas because it’s just not necessary)
JHM STOCK FUELLING vs. Aviva who used 2 upgraded fuel pumps - this is a huge difference, and i can just picture the guys at Aviva and at TTS saying ‘how the fuck did they do that???’ Classic JHM
JHM full interior vs. Aviva removed rear seat/seatbench - negligible but let’s mention everything
JHM LW front rotors vs. Aviva BBK rotors - I reckon the Aviva car had reasonably heavy rotors because someone said they’re 380 mm. That would likely mean the weigh what stock RS4 rotors weigh…so this is an advantage of about 10 lbs to JHM (rotating…important)
JHM LW rear rotors vs. Aviva ??? stock??? - another few pounds of rotating mass removed. Minor difference.
JHM looks to have Michelin PSS tires on this car vs. Aviva who mentioned they had Dunlop Direzza. Not sure on sizing or weights, but looks like a minor advantage to JHM.
JHM 100 to 200 feet of Density Altitude vs. Aviva who were -700 to -900 feet. This is a massive difference.
All in all the differences in weight aren’t that big. Sure the Aviva guys had the seat out but the JHM car shaved some rotating weight so that’s overall in JHM’s favour. However it’s minor. But when you factor in what JHM is accomplishing with WAY less boost, on stock fuelling, and with a car tuned for 91 (but running 93) it’s pretty staggering.
When you consider the JHM stage 2 intercooled kit costs $11,000…which is the same as the Aviva base kit…that’s incredible.
When you consider that JHM stage 1 non-cooled kit is $7950, and went mid-high 11s @ 117-118 MPH, that’s also incredible. $3,000 less than the competition.
