 OHV V8 vs. (D)OHC V8
http://www.caranddriver.com/article.asp?section_id=27&article_id=8025
Päris huvitav lugemine aga ma kahtlen, kas Toyota hakkab OHV V8 mootorit tootma, imago ilmselt ei luba. |

OHV V8 vs. (D)OHC V8
Juba toodab:

Samuti on praegu NASCAR Craftsman Truck series 2. ja 4. mees Toyota roolis ja Toyota tootjate arvestuses teisel kohal Fordi järel.
Lisaks kvoot ühest teisest foorumist:
"I had a fascinating conversation with Lee White of Toyota recently about their NASCAR engine. They had no production baseline engine to present, so they went to NASCAR and said essentially "where can we start as a baseline?" NASCAR said the engine could not be better than any of the existing NASCAR engines in any single aspect or dimension (for example, cam height could not be better than the Dodge, intake port volume could not be better than the Ford, etc and so forth.) So Toyota asked well, what are all those dimensions? NASCAR replied well, we have never really compiled all that data. In efect NASCAR could tell them what was illegal, but not what was legal.
So Toyota went out and bought several examples of each of the competing engines and totally reverse-engineered each one, nailing down from five to twelve THOUSAND dimensional hard points for each engine. The box defined by that data became the design template for their engine. Seems like quite an interesting and challenging project, but a very peculiar one." |

OHV V8 vs. (D)OHC V8
Üldiselt on mujal tavaautomootorites 90->04 ajavahemikus trend olnud DOHC 4-klapiselt SOHC 4-klapisele. 4-ja 6-silindrilisele (s.o üherealisele) mootorile OHV vaevalt et tagasi tuleb-seal pole ei erilist kulu-ega lihtsuse vahet. V8 on teine teema, 1 vs 4 nukka on teine teema nii mehaaniliste kadude kui hinna osas. GM ise läheb ju 2xOHV mootorite peale
