Speedmaster aluminum heads
:rolleyes:...... righty O
Pingity, ping, pingity , ping, pow.:lol:
Since this is the racer's Forum,
I didn't want to say more;
but somebody not you fishmens, poked the bear, making it personal; so
Firstly;
I Ran it like that (post 19) for an entire summer, and, with a regularly scheduled teardown every winter for inspection; there was no sign of detonation. It was the strongest bottom end I ever had and my favorite combo.
On the next combo, a one-size bigger cam, the pressure came down a tad. I really missed that. So much so that I swapped the 2.66 low out for a 3.09. This allowed me to retard the cam, and I picked up a good amount of top end. Car went 93 in the Eighth @930ft and 3467 pounds, me in it. with 3.55s no less.
But you know;
according to some
it can't be done.
Like said; I'm a streeter with a clutch; bottom-end is everything.
With the GVod used as a splitter, my new combination of gearing, gets me; Four ratios in the Eighth, namely;
3.09-2.41-1.92-1.50 ; which in Roadgears with 3.55s is
10.97-8.86-6.82-5.32 ;
and 93mph is 6170 ;
and it takes off like it had 4.10s
First-over gets me 50@5100/60@6400, Second is 60@5100/75@6400; Power Peak is ~5100
This combination was a culmination of five years of experimentation which ended in 2004/05. After that, it was settled and I just drove the crap out of it. Both the car and I are semi-retired now. Every once in a while I take it out for a spin,
just cuz..........
Secondly:
Of course you knew he would Always makin it about him. lol
It wasn't about me until some of you guys made it so. I was just trying to help.
But you guys are the guru's, and love to put me down.
I'll tell you a couple of things tho;
1) I'll never go back to low-pressure, and
2) I'll never go back to iron heads, and
3) I'll never go back to low-temp stats
4) regularly-scheduled inspection teardowns
are cheap compared to dynomited engines.
5) a lil too much ring gap is, by far, better than tearing off lands. For a Street-car, now; If when you shut your engine off, ten minutes later, it won't crank cuz the pistons ain't moving; do yourself a favor, don't bandaid her up with cooling system mods; just do what needs to be done. She needs to come apart, and get fixed. Loosen up the skirts and open up the gaps.
6) If there ever is a next cam, it will be a solid lifter.
and Thirdly
Damn. Still preaching nonsense about aluminum heads and compression ratio. You are WRONG dude.
If this is true, then I am happy to be wrong.
I could be wrong about a lot of things; like, the shape of the Earth, the Second Coming, The THIRD Resurrection, the Four Corners of the Earth, and the Seventh-Day Sabbath...........
Fourthly;
Can you run a streeter at 195psi with iron heads?
Last I checked, not NA on 87E10.
With alloys, I've been right around 180 now, for going on 9 years. yes still and always on 87E10. And BTW, until October 2022, it was still on the original Champion copper plugs installed in 1999. In 2004 when I ran that Eighth, the plugs were already over four years old, and likely had close to 40,000 miles on 'em.
Once again,
jus saying.
