Chops@MVP

iTrader: (8)

Hello gents,

MVP is coming to the table once again. We’ve listened to the owners and are proud to offer a middle of the road upgrade for those looking for a bit more power for a reasonable price. What you see below is a new more aggressive camshaft profile. We use the best of the best stock cores, and modify them by hardwelding the lobes. We modify the lobes only, and leave the base circles intact. This method gives us the highest possible quality. Check the pictures below.







Availible grinds are:

208@ .050, .354 lift

218@ .050, .356 lift

226@ .050, .360 lift

214@ .050, .368 lift (the grind pictured above)

227@ .050, .400 lift

230@ .050, .406 lift

Compare to a weak stock profile of 188in / 194ex, .314/.315 lift.

This is a good middle of the road start into the world of Lexus V8 performance, and something that we very much believe folks are looking for. The mildest 208 grind can be used without controlling the VVt-I, however the heavier grinds may require VVt-I control to avoid valve to piston contact. As a general rule, the milder the grind the more midrange, and the more aggressive the grind the more upper rpm HP.

Pricing is set at a very reasonable $1900 for the set of 4 cams plus a $750 core charge. As with any core charge, MVP will reimburse the $750 into your account once your original 4 cams are shipped to us.

As an option we can include a set of 32 V8 valve springs for $450. This will eliminate any chance of valve float or coil bind.

Would these work in my non VVTi Sc400? And how is idle with these cams?

c0wboy

These particular cams won't work with non VVt-I 1uz cams, however Robert@MVP can source for you a billet set of cams for that motor. The idle on the milder grinds is smooth, yet more aggressive than stock. Same idle. On the heavy grinds, you can expect to raise the idle and have a good lope. The payoff is more duration, and more lift at higher rpms.

Thanks!

OK, so what about us fools that don't understand one word of the specs above ? I know one thing.... I WANT ONE! (or 4, I guess...) Will this do anything for the much talked about problem of off-the-line-hesitation? Which grind is best for someone like me who just wants more linear response across the entire rpm range? Also, what other work/parts/etc. are needed or a good idea to do for this mod (other than the valve springs) Finally, are these ready to ship?
Thanks, -Steve

Hi Steve,

I think the hesitation may be a function of the drive by wire system. The cam specs do take a little studying to understand, but one thing is clear. Any improvement over stock will give a real performance increase. It really looks like you've got the basics covered as far as basic performance upgrades so the next logical step would be cams. If you're looking for more gusto in the mid range carrying over to the upper rpm, I'd suggest a mild cam like a 208. It keeps the smoothess of the motor, and gives more of a punch. It'll sound like a million bucks, too. I would suggest a set of valve springs as well to cut out any possibilty of valve float at high rpm.

We don't have a set of 208's ready to ship immediately, but if you want to put in the call to Robert, we can get the ball rolling. We 3uz cams aren't easy to come by, but we have a good source. Once we have the cams in, we'll get them put through to be manufactured. They don't take all that long, the facility is running fairly quick right now.

Thanks Steve,

Eric

Thanks, Eric. I'll contact Robert.... and see where we go from there.

c0wboy

Thanks Steve, Robert and I were going over the details this morning. Let myself or Robert know if there's anything else we can do for you,and we'll get it all sorted.

So what kind of hp gains can be expected from runing a 208 grind on a setup like intdiamond has? Whats a good VVTI controller?

c0wboy

Intdiamond has many bolt ons, and with addition to the cams you could be looking at between 75HP and 90HP over stock. Still safe for a stock motor, and giving the car a real sport feel. A good VVt-I controller seems to be the Camcon VVt-I controller. I don't have any direct experience with it, however from the testimonials of those using it now on Toyota vehicles, they are very happy.

Thanks!

Eric
