while i admire what zzp has done that post right there is just ignorant. If he said he wanted 400whp then id say go turbo. While you guys make awesome products there is no need to give mis imformation to promote products. And actually i run many of your parts on my car and have had good results. I run just as fast as tims ion on my stock 72k motor

dont need axles
LSD isnt as big a deal as people are making it.. is it nice? for sure.. and definitely worth it if u r driving the car hard a lot. for a car being daily driven mostly. not needed.
no internals needed
if u have the powell motor and trans mounts.. no need for ingalls.. will just add vibs inside cabin
for example
i made 330/272 on TVS 2.9 ring, CIA header, 3 inch downpipe WITH a hi flo cat, 2.5 magnaflow cat back, OTT heat exchanger, k&n intake, custom tune... and meth
no dual pass
no head work
No over the top exhaust
60lb injectors...
0 internals... stock longblock
if u wanna make 300 to 330 on a TVS. go do it.. dont stick with the M62 if u dont want to.
IIRC only 1 or 2 made 300 on M62 and that was with E85

three i can think of quickly are a guy on the redline forums WAY back in the day - dont remember his name
paul from NY
ebristol
just the three i can think of real quick. i know there was more....theres a thread somewhere about it on here.
but your right tho too much work to do it with the m62 when you can just go tvs, less stress on everything and not so much heat

Yes, but not the first production run. I know cars with a build date of May of 05 or later had them. Might be some earlier, but I know the March 05 cars did not.
Must mean I have driver mod 
With cooling mods and E85, the first limit people hit with a TVS is the stock fuel system. That is why most people mention that 330whp as cap. I hit that cap and did not feel like messing with fuel system upgrades so I sold the TVS.
What I should have done, and I wonder if anyone has tried it yet, is test different ethanol blends. Extensive testing has shown diminishing returns of hp and fuel economy past an E50 mix. I wish I would have tried some different blends to see how far I could bring down the IDC on 80s.
Running a 2.8" pulley with an E47 ethanol mix should put most TVS cars around 340-350whp. If the fuel system could handle a 2.7" on a E47 blend that would mean 350whp+ with a good tune.
I have also considered a E47 mix on the M62 just to get some of my fuel economy back.
with cam gears i think the time to tune and dial them in wont be worth the minumal power youd gain. Ive talked to a few people on this topic. Once i see a can dynoed with a blower particularly the TVS and they have good gains without losing from the low to mid range then ill get a set. Even area47 went back to the stock cams and he had the gmr cams and the 272's

And I doubt there will be no gain if the time attack setup or whatever john was involved in ran them
adj cam gears would be used if the cam event timing is off. if the event timing is off you can loose hp generaly if you deviate from the specified cam event timing you loose power here is a short on why to degree a cam
Talk to any cam grinder, engine builder, or racer and you’ll find overwhelming agreement that “degreeing-in” a camshaft is a vital step along the route to optimum engine performance. At first that may seem strange because “degreeing-in” a cam pertains to checking the accuracy with which it was manufactured.
The purpose of degreeing a cam is to insure that the cam is phased correctly with the crankshaft, per the cam manufacturers’ specifications. You’re insuring that valve opening and closing events are in accordance with specifications, regardless of the cause. Actual valve opening and closing events are influenced not only by accuracy with which a cam was ground, but also keyway position in the crankshaft, crank timing sprocket, dowel pin hole position in the cam sprocket, and accumulation of machine tolerance also play a major role.
and so far from what i have seen the cam timing isent off enough to make a difference so adj gear on stock cams wont do **** and the zzp cams are checked before they leave zzp to ensure the specs are accurate

i have seen zzps cams not interested in them and i know far more about cams and overlap from adjustable cam gears than you could ever know. All i stated is if zzps cams are zomg why havent we seen dyno numbers to prove it?(in particular on a blowered car) exactly. The stock cams are fine for me. And in my original post i stated that adjustable cam gears are a waste of time and money.

well i would have to dissadree with you on the zzp cams from first hand experience the stock cams are great for road racing the stafe 1 zzp cam would be also the stage 2 cam from 3500 and up it realy gets with it hard
