Beyond saying that knowing what I know now , that turbocharging makes a lot of sense , I know very little about it. But I have a good handle on humorous , and I think this is it. Hope you found it as funny as I did. I likey

haha that is a great meme.
I have the boost itch pretty bad. I have an R1 block, enough fuel system for 1200HP, and multi point EFI with pretty much limitless capabilities already. From just a little bit of figuring and looking around it would cost me $6000-7000 to do a pro-charger setup that would support 800-1000HP and that is without touching the motor. I think I could do a turbo deal for less than that including putting in a stronger piston and a cam suited for boost. So now all i need is a little money and time...easy right? lol

Having dabbled in the diesel turbo world I will tell you what I know (what I’ve been told) to the truthfulness and accuracy I can not attest. Turbo lag is caused by an exhaust housing that is too large for the amount of exhaust gasses exiting engine, thus causing a longer time to spin the boost wheel causing the lag between the foot to the floor and the turbo catching up. Exhaust housings that are too small are also an issue. We used to take the 20mm exhaust side housing off our hx35’s and put on 16mm ones. There were also 12’s but we found this caused exhaust temps higher than desirable without water injection to keep the pistons in it. I’m sure there is a YouTube video somewhere that explains it in better detail. https://youtu.be/5bGLcoSU73I

The newer ones don’t have this issue, they have diminutive exhaust housings some as small as 9mm to lessen the problem, however it adds a totally different issue in high EGT temps when you start hotrodding them.
