Small Block vs. Big Block

Sorry Tom, thought the 10.60 was run by Dave at Fastlane. Anyway, this is the same type of discussion on ANY other board, no one ever wins (except the hard headed big block guys :D)

Mark, mine scares me too. As I've told many a spectator that comes up to me, when I stop being scared of it, it's time to get rid of it.

Dan, fugot you had a fancy turbo under your hood :D
 
That's the way to keep it Mark. I have found that when you sit down in the seat and strap yourself in if you listen very very carefully before turning the key, you can hear a whispered voice saying "Disrespect me and I'll kill you". Listen to the voice.

This is without a doubt...the best advise ever posted on this forum.

Tom's words should be on a plaque and mounted in every Cobra in the club.

(And on a few motorcycles as well....)

Many of us still bear the scars and pins of not listening to that inner voice....and we were the lucking ones.

Mark you have my utmost respect... for being honest... and saying what all of us feel but rarely admit.

K&K

That's what happened to me with my C5 Vette. I found myself doing 140 mph runs on Hwy 100 - not worried, and doing it quite often - and got bored - kinda weird really. I wanted something more, something raw - found the Cobra. Wow - perspective - 120 in a Cobra scares me to death. If this car had a six speed - I'd be dead by now.

I like this thread, but it's strange isn't it. We all crave the power, but a Nissan Altima will run 140 easily. So we have these cars because of more emotional reasons and the reactions of ourselves and others.

OK - now back to the fun. More soon.
 
Exactly. The scariest car I have driven was at the Petty Racing School. The instructor went almost as fast in the big van around the track, but open, loud car, set up to turn to the left 134mph felt like the car was going to fall apart.

I think after having the cobra now I would like to try Petty again.

It is funny though, you guys talked garbage for the first couple pages then clammed up later. I see some pretty good grudge matches coming at RnG:eek:

My $.02-Tim does a great job at RnG. I would much rather have control than be on the track with a bunch of guys that have "real race cars" and big budgets and don't care about safety.
 
Hey, just cause you're on my side doesn't mean I won't be gunning for that 1:22:00 or whatever that slow a$$ time was :D

David,
I know a little about everything and a lot about nothing :D.

Ahhhhh Humility. It sure is refreshing to hear someone as knowledgeable as Tom not acknowledge his depth of knowledge, wisdom & intelligence, as opposed to being arrogant, prideful & condescending. It is my honor & privilege to call you a friend.
 
9 lbs. is probably about as far as you want to take it for reliable street use with the bosch bypass valve you are presently using (yeah, I looked under your intake tube :D). Just because you are running a 9 lb. pulley does not mean that you have 9 lbs. of boost. Since you have the "X" heads which flow a lot of air, you are running with a decreased resistance to flow and the actual boost presence is reduced accordingly. The only way to know for sure is with a vacuum/boost gage and somebody to watch it while under full throttle.

After posting that thread i went out to the Powerdyne site and did some research. They were quoting an "Effective Compression Ratio" which is based on a calculation between your piston compression ratio and the amount of boost. Powerdyne states "Under normal circumstances with a Centrifugal blower you can usually run an Effective Compression Ratio of from 12.50:1 to 13.10:1."

I think I know what my pistion compression ratio is, but like you said, with the X heads it may be running a little lower Effective Compression Ratio. Where can I get one of those gauges and can it be a temp mounting or does it have to be permanent. If it's temp, then we could both use it! I don't know about you, but I have been known to run mine at full throttle for a short time. :rolleyes:
 
Oh here we go. She's been under full throttle, just not over a 100 mph in our cobra yet. I have yet to live that one down, so thanks! :D I know you like a big block and I like a small block. You can get a SB to produce HP as well as a BB and in some applications better. I just feel they are better suited to a road track type racer. A Big Block you get that deep power. You know, for like a tractor or something. :p
 
:D:D Glad I didn't have a drink of water, think it would have come through my nose! :D Seen the new Chevy commercials where Howie is talking to the guy in the red cap about trucker stuff? BB = the Howie; SB = the Toyota guy
 
The one thing you cannot replicate in a SB that a BB produces in excess is Torque. Need I remind all of us HP junkies that Torque is the mother of all forces that kicks us back in the seat from a dead start. Lots of it at low RPM's in Tim's and Mark's beasts. I've ridden with Mark (and lived to tell the tale) and I was converted. I still like what I am building because I want something that is streetable and gas friendly, but there is no replacement for cubic inches. HP comes on at higher RPM's and sure it will make you go faster!

There Tim and Mark, just threw you guys a huge bone. Don't fight over it!:eek:
 
Man, just when you think you know a guy! A modular guy at that! That's ok Scott, I know you're just being nice. They're both great guys.
 
My engine has the smallest displacement of the crowd (281 c.i.). But I'm okay with that. It's not about size, just how you use it...





(I'm feeling light headed tonight after two beers so there, I really left the door open on that one)


EDIT: Mark's motor is 588. The modular motors are 281. Mark's engine has more than twice the displacement Wow.
 
Ok you asked for it and I coul;dn't agree with you more. You can be a BB guy and go straight in with full power or you can be a small block guy and work the curves and angles for a longer more enjoyable ride. Plus a 1/4 mile is over in less than 12 seconds. That's not good.:(
 
Hey Tim

Tim - don't you just love our small blocked friends. They're so smart about their compression ratios, cams, computers chips, modular this and that, turbo super power adder thingys - all that technical stuff. It really is quite impressive that all that stuff comes together for them. In our tractor engined beasts, all we really have to worry about is - where the next gas station is located, and if our rider is interested in ear plugs.:eek:
 
I was wondering when you'd show up. It would be interesting to see a time graph of whn posts from each paid member occur. I bet you definitely see trends. Like you after 10 PM - midnight.

Hey, I resemble that comment. Did you guys know that my engine computer, and special wiring, and harness/panel cost more than my engine. That's electronics for you.

Mark - you forgot one more thing...speed dial number for the shop when you blow things up with all that power.
