why???
we're getting 700+hp out of N/A 3rd gen engines now with only 16 valves. Start adding boost and I've seen cars with 700rwhp from 346ci. All I can see is added weight and complexity with nothing to show other than a bragging rights for having a 32v engine

DOHC is cool!
I love my DOHC with VVT in my 1994 Infiniti Q45t. The car has 170,000 miles on it and regulary runs to 7,400 RPM in the first 2 gears on the dragstrip for fun. The engine sounds great, and the Magnaflow exhaust is a blast. 4.5 litres and 330 HP and 350 ft/lb torque is not bad. I have a couple videos on You Tube. Do a search for "Q45".
My last Q45 had 255,000 miles on it when I ran for 15 minutes over 7,000 RPM in third gear, and 140 miles per hour. I had to show some crappy Mustang Cobra what a 10 year old 4-door luxury car can do. The guy could not catch me - and he tried. I had issues with drag on the closed circuit I was running on. The transmission was getting quite warm, so I shut her down. The top speed in 3rd gear at 7,400 RPM is 155 MPH on the dyno. I put another 30,000 miles on the car before I sold it.
I have a 4.11:1 rear for my new car and a stronger transmission with a cooler and a 3K stall converter. This should get me in the 14 second quarter mile range.

just think, with all that flow you would use a cam that has a duration of almost 200 and lift in the low 400 range... talk about long life of your valve train...and with those baby specks it would still out flow the standard head by 2:1

There is a lot of information out there about this company. Seems to be VERY shaky at best and dishonest at worst. Lot's of pics but no heads... I don't think I'll be sending my hard earned money to them anytime soon.

be careful guys. Although on smaller engines a DOHC design can be advantageous... in larger V6 and V8's, it adds too much weight, too much rotating mass, and too much $$$.

The guy who designed these does not have the best of reputation. Not to mention I am almost positive no one actually has a set of these. Our simple 2 valve heads flow amazingly impressive amounts of air. There is just something to be said for engineering simplicity.

This place had a horrible reputation, but was recently bought out I think and apparently the guy was trying to turn it right side up.
That being said I haven't heard of them sending out a new set of heads in about 5 years.
The heads that are out in use have been passed around pribvate party to private party.
I would be very leary of sending any money to this company.

They've been advertising LTx heads of the same ideas for YEARS now, yet to my knowledge there's not a set in a running car out there. A couple of guys got real close, but watching their work unfold was enough for me to turn my head. For a "bolt on" installation, they sure required a lot of custom work (headers and intake manifold among things). Same goes with the LSx stuff. There was a big thread on these over at ls1lt1.com a while back, and the advertiser there made mention of an approximate 1/2" wider surface mounting width on each side for the exhaust manifolds. May not seem like much but could wreak havoc on an already tight application.

If you're talking about the pics on the areoengineering website, that engine is not a DOHC.... the single cam is still in the block. Mike Mercury is right..... a DOHC engine in a Corvette would be heavier.... and, most importantly to a lot of folks... much more expensive, if it delivered the performance that our "old technology" pushrod engine does.
