Someone had to call him out on it. You can't go posting dyno sheets that are not yours, and claim them as your own....

That's what everyone thought back in the 90s. However, those myths have been debunked many times.

What myths? I cant say for certain bout the excess wear but I have a stoker and the dyno is nearly identical to the stock block so there is no power to be had. The boost may be negating the minimal increase in volume but being so small I doubt the gains will be noticeable. If there were gains to be had you would hear bout it like stroking the old 302s to 347.

You're the first person I've heard say there was no power to be had in stroking a 4.6...seriously.

A stroker will make a minumum of 20rwhp/20ftlbs more than a stock ci engine with the same compression and cams. Because of the added cubes, the stroker will make peak power at a lower RPM than the 281 ci engine if it has the same cams as the smaller cube combo. Add cams that allow the stroker to take advantage of the extra cubes and the hp will peak at a higher RPM and the peak hp gain will be much greater.

I've never seen a 4v or 2v stroker not gain a significant amount of hp/tq.
You obviously aren't dealing with engines that were put together or spec'd correctly.

I replaced my shortblock and actually had a slightly higher CR and made the same. You do realize its a gain of only 21ci? So your saying the 4.6 makes 1whp per cubic inch? That would mean they would put down about 280 hp to the wheels stock.

Like a said the boost will force air into the engine making the 20ci gain less noticable since the blower crams in a fairly fixed amount of air. Ive never seen any dynos myself of engine making more power.

Also for the grand or so extra for a stoker is 20 hp really worth it? If your goin all racing maybe, but for most they can get alot more power for the money.

An n/a gain of 20rwhp is a 40rwhp gain at 14.7psi boost.

Your not comparing apples to apples anymore though. With NA the added stroke increases negative pressure in the cylinder as well as increasing the veloctiy of the incoming air. When your boosting the physics of the air wanting to equalize pressure will be greater than the velocity and out weigh the slight negative pressure increase.
