Going over those numbers ….
FYIThe Crane cams were used by Toyota as TRD upgrades for the 20R and 22R(E).Gnarly, have you tried advancing or retarding any of the cams?
Beat the crap out of my buddies engine today with the Holley sniper some what tuned . Still needs a little more tuning . Made 163 hp and 179lbs of torque. Those are some good numbers. Head is my cnc ported stage 4 head with a 272 -262 cam. 10 to 1 compression.That was from Jim Putney yesterday..
So many other cam grinders out there. I've used WEB cams in other engines. Curious about a couple of their grinds for the 22R/E. What do you think about their 94, 94a and 391 grinds? http://www.webcamshafts.com/pages_vehicles/automobile/toyota/982.html
OK here's just 1 RPM range - 1800 thru 5400 in 400 RPM increments:Pk Tq - 153 @ 3000Pk HP - 114 @ 4600 and 5000 - low HPAvg Tq - 134Avg HP - 90.4That cam is 8 degrees advanced cam timing!!At 4 degrees advanced:Pk Tq - 154 @ 3000Pk HP - 120 @ 5000Avg Tq - 136Avg HP - 92.4At zero degrees cam timing:Pk Tq - 155 @ 3000Pk HP - 124 @ 5000Avg Tq - 138Avg HP - 93.6At 1 degree retarded cam timing:Pk Tq - 155 @ 3000Pk HP - 125 @ 5000Avg Tq - 138Avg HP - 93.9Gnarls.
Surprised you didn't notice the 94a has the same spec as LCs EFI pro cam.
Thanks for pointing that out. Way too many cam specs to remember unless I'm actively doing comparisons.So LCE buys, or has WEB grind their cams? LCE has an engine dyno, I wonder if they actually did testing on this cam.... or they relied on WEB's dyno tests?Gnarls.
No such thing as an easy anything swap.
. At stock timing I get detonation with 89 octane fuel and an occasional tick with 91. I believe the squish gap is excessive. I might need to use a thinner gasket.
I may be confused... anything is possible now at my age....I thought if the squish gap is too small that it may cause detonation?If you are pinging, wouldn't you want to make the squish gap larger... THICKER gasket???Too much quench can cause detonation. But doesn't a smaller quench area raise the static compression ratio?Gnarls.
.015-.020" gasket? Where'd you get that thin thing? Piston to deck means below the deck? If so, .008" +.015" .023"That's a squish, or piston to head clearance of 23 thousandths. If you were building an engine that you knew the max operating temp, expansion coefficient, and deflection/stretch of the crank, pistons and rods you could calculate everything to the gnats ass and build to a .000" gap. I believe the compressed thickness of the stock 22R head gasket is either .050" or .060", so unless you have an aftermarket gasket your gap would be quite a bit more than .023".
Lewis would be right in being finicky about that 75 lbs as the distance at which that force is applied is important. I mean, is it 75 lbs at a foot or 6 inches or 6 feet. Makes a difference. But for those that just assume it's at 1 foot...… Eh. Yep, just proper to say foot pounds when specifying torque.
I don't recall ever seeing or reading any torque spec for head bolt on a 22RE other than FOOT POUNDS.
Bravo Sierra. After being around automobiles, go-karts, sand rails, drag racing, 4-wheeling for most of my life. My dad was an auto mechanic and by the age of 10 I could pick out every tool in his tool box when he asked for it. By age 5, I could name the manufacturer of every car in out town. In all my years, I never once had anyone ask "How many feet are you torqueing your bolt?" when discussing or describing a torque spec for a head bolt. I don't recall ever seeing or reading any torque spec for head bolt on a 22RE other than FOOT POUNDS. Lewis may be suffering from atelophobia, laced with a tad of NPD (Narcissistic Personality Disorder). His posts almost always have a "police" presence. Lewis..... Gnarls.
