NASA TT classing for 330 ZHP

I've seen a number of ZHPs built to run in TTD. But after reviewing the base classing list, I'm curious...

I see the 01-06 225bhp 330 with a base class of TTE*.

But I don't see any reference to the ZHP package?

My Ride: ZHP
So my research has led me to the conclusion that the the ZHP would be classed as a normal 330(25bhp), but you would be required to take points for the aero(front and rear bumper, etc) and cams.

Can anyone confirm this?

Yes James, you are correct. Here's the breakdown.



The "Base Trim Model" 01-06 BMW 330 (non-ZHP) has a base class of TTE* and a min weight of 3285 pounds. The * was added in 2016 and costs 7 mod points, ouch. Yea that wrecked all sorts of plans on my TTD prepped 2001 330...



The "BTM" or Base Trim Model for the E46 does NOT include the ZHP bits. Obviously the cams cost you points, that's clear. The NASA TT National Director hasn't made a definitive ruling on the ZHP front end, but it could ding you a lot. No idea about the rear either. It could all add up.



Of the 3 main E46 front bumper covers we have explored for our TTD E46 330 Coupe, the "BTM" 330Ci unit costs 0 points - so we've kept it. We think the E46 M3 front end costs +6 (3 for "air dam", 3 for "splitter"), and the ZHP could cost as much as +8 (3 for "air dam", 3 for "splitter", 2 for "canards").



So we've kept the janky old 330 front bumper cover (and cams) on our 330Ci build for the past 2 seasons. We have gone to great lengths to keep this car within TTD class, and do far its paid off with wins, TTD track records, and two regional championships.

But as many of us know, TT-Letter classes are quickly becoming extinct. The replacement of TTA with TT3 happened in 2013 (we jumped into TT3 with success using a Mustang), then TTB became TT4 in 2017. Rumor has it TT5 is to replace TTC in 2018, and TTD might not last much longer...



I'm getting ready for a jump from TTD to TT4 later this season. This move is both good and bad. TT-Number does away with all of the points chasing, as well as the huge discrepancies and penalties for what "starting models" you begin with - like the ZHP penalty you are running into. Its bad in that TT-Number lets you do a lot more mods for the same power-to-weight class...

See more details on the TTE->TTD->TT4 progression in my build thread, linked in my sig below.
