quench vs no quench?
From what I understand, that is correct.
Mr Mad.
Question: When dyno testing and engine how do they determine the HP number??
How do think HP is determined? Just like all the jokers say, it is a mathematical calculation. But all that is IRRELEVANT to the discussion.
All you idiots should be running diesels. They make huge TQ compared to HP. What I'm trying to get you think headed guys to consider is this: if torque is your do-all, be-all, end-all you are WRONG at best. Most you you don't think past the end of your noses.
Let me say this one more time, then I'm done trying to have a conversation with guys who would argue with a sign post (or put me on the dreaded "IGNORE" list...stupid thing really).
Did an engine for a guy back in 2006 (or so). In typical moron customer fashion (most customers don't know the HALF of what they think they know, but the interwebs have made them experienced engine builders don't ya know?) he says "I want to make 800 ft-lbs of torque (not knowing that it's actually lb-ft...but what does semantics and FACTS have to do with anything right??) with this here engine. I, naturally say WTF for? How fast do you want the car to go? He says "very low 10's, so I don't need a license". So, I tell him "you need about 700 HP to move that pig you own (3800 lb car) to low 10's, and that will be about 1.5 HP/CI and you will end up with about 570 on TQ". He don't want that. Says it's his deal, wants that big TQ and says if it makes over 800 on TQ it will run low 10's all day long. I tell him, no it won't. With your engine geometry, it will make way more TQ than HP, and it will ET off the HP number. So I said "do you want to go low tens, or tell everybody how much TQ you have?". Says I want both. I say can't do it. Since a sucker is born every SECOND, and I KNEW he was on the interwebs and was now an experienced engine builder and all around hero, I said lets make it fun. If it makes 800+ on TQ, I say it will run what the HP says it will. You say if it makes over 800 TQ it will run low 10's. If it does what I say, you owe me a cool G extra. If it makes 800 on TQ and runs low 10's, I write $2500.00 straight off the bill. Game on.
So to save you all the reading, he got exactly what he wanted. It actually made 865 TQ and 425 HP. So the customer was squealing like a pig in poop. Installed the engine in the car for him and had it all real nice. Off to the track, the customer thinking low 10's, me telling him 11.40's in the mid teens on a good night.
Needless to say, I won the bet, took the money and told him that TQ is for posers. Yes, you need torque. But to deliberately make torque at the expense of HP is D-U-M-B.
BTW, that night, the car was in the 11.60's. He did a little chassis tuning and it's best EVER was 11.40 something. He was so sick that he sold the car (out of my shop BTW) and the carnival huckster kept telling the buyer about all the TORQUE it had!
So if you bothered to read all this, maybe, just maybe you learned something. There is not a reason in the world to build a combination that has, say 670 HP AND 700 TQ unless you think all the faster you want to go is what 670 HP will take you at your car weight. It's really that simple.
Keep on arguing and you will STILL be wrong. Not because I say so, but guys like Harold Bettes, Jim McFArland and many others say so.
