Ask yourself this: If there was a product that cost less than $100 and improved fuel economy by 31% don't you think it'd be included in every car that was built?

There's nothing inherently wrong with a pushrod engine, they're very compact when compared to an OHC of similar displacement. I asked because you just don't hear about too many recently developed 4 cylinder race engines that use pushrods.

That has to do with compressor efficiency, not conduction. At 25 psi a stock CT is way out of its efficiency range. This is just a random compressor map I'm using for illustration, not an actual CT26 map: If you look at the contour lines you'll see percentage numbers (74%...

Nearly all the heat above ambient in the air charge is caused by compressing the air. A turbo is hot but the air is inside of the turbo for a very short period of time. Because of this, heat conducted from the turbo to the air charge is negligible.

Having an intercooler is obviously better but going without isn't as bad as you'd think, particularly if you're running mild boost. Roots style superchargers have a lower compressor efficiency than a turbo (more of the pressure increase is caused by heat, so you have less actual air mass per...

There are a few older turbo cars that didn't have an intercooler, but most people who bother to say that are trying to sound cool.

Did you say it was a pushrod engine?

Thanks :icon_bigg

It is all in the tune, but there's not much room for error at that power level on the stock pistons. John Lunsford is making over 400 hp at the wheels on stock injectors and only using a Lexus AFM and an AFPR for tuning, but I wouldn't recommend that other people emulate him. John and Dr. Jones...

I don' know if there's some magical tally keeping track of our good and bad actions but I believe in a form of karma. Most people who are jackasses tend to be unhappy. They treat people like crap, are despised for it by others and usually don't like themselves. They may or may not have nice...

:umno: I've yet to hear of a high horsepower 7M fragging the stock rods or the crank. The stock pistons seem to do OK in high output engines but should be replaced if you're looking for over 400 whp. I personally believe they will work past that point with proper engine management. The...

Can you weld?

Very nice! :drink1:

Whoa, this reads like a SF thread. All we need now is someone to call something gay, then bash a Honda and it will be complete. "The CT-26 can't make that much power, it's gay. Did this guy learn to read a dyno sheet from an H-badge zombie?" Lighten up a bit folks, this is supposed to be a...

They do but not too many people seem to know about it. The PT cruiser GT is powered by the same engine with a different intake manifold.

Forged pistons can rattle a bit while they're warming up. They have a higher thermal expantion rate so they need more piston-wall clearance when cold. They should quiet down once warm though. Have you tried playing with a mechanic's stethoscope (or a long screwdriver with the handle to your...

Supras don't tend to rust but after 15+ years the rear hatch can develop a leak around the rear spoiler, the weather stripping can fail or the tail light seal goes bad. If the owner is negligent and doesn't repair the leak water will collect in the tire well and you'll end up with some rust.

Most OEM injectors, particularly small ones, don't show much if any flow improvement above 60 psi of fuel pressure. With a 12:1 you'll be getting 60 psi of fuel pressure around 3 psi of boost. If you're relying on a 12:1 FMU your fuel curve will go from stock a/f ratio, to pig rich then it'll...

I've seen one run low 14's @ 100.XX mph stock. I wouldn't buy one but it's the fastest late model for your money right now. It sounds like there's some misinformation floating around about that engine. It's not a stock neon engine with a turbo bolted on, it's an entirely different block. It...
