Emulating a Callaway TT Engine, sorta....

Post by *89x2* »

Following the success of the RPO B2K, Richard Holdener built something "similar", but not really. Watch as he explains:

Holdener was early on the flow material to port an intake, Extrude Hone. I think his name was in Car Craft Magazine in the early 90s and really was on the cutting edge, no pun intended.

I often wondered how a TPI manifold would respond on a Callaway car which was extruded with that material. Here's more of his videos, even though I think he's a Ford fanatic, https://www.enginelabs.com/author/richardholdner/

Has anyone heard of using Extrude Hone on an L98 with good results :wtf

The stock TPI runners were already extruded. The base and plenum could be done. :beer

Did Callaway extrude them, or was it the nature of the material of the runners being smooth bore tubes? :pop

It was how they were originally manufactured. :beer

That's really interesting. I looked for TPI Extruding and came across this data which seems plausible The only problem with the superram is the fact it fits so few vehicles with either intercoolers in the way, or on a 4th gen f body, other mods need to be done. The superram makes lots of power, but the shape is limiting for packaging or fitment across more cars. :bs

The old AZspeed&Marine/TPIS runners looked like stock but didn't properly fit between the intercoolers. I had them on my car and one runner had to be dimpled to fit. It wasn't a large indention but was necessary.

The best intake mods, that you can actually find, would be an extruded honed large base with extrude honed SLP runners and a stock throttle body ported to 52mm

The thing is, on a Callaway, is it okay to put SLP runners in-place? :stop I passed on a set for $400 which were never installed, for the 1989+ TPI cars, although the earlier ones can be fit if one blocks the cold start injector orifice :wtf The Arizona Speed and Marine ones are interesting, and I watched them being made, some decades ago when I was at their shop looking at their 502 big bock efi setup. It was a hole in the wall shop, outside Phoenix, located in a strip of drive-in warehouses. I think a 7-11 has more space inside. Smaller than I expected however, low overhead. It was a couple guys, and then a lady at the desk and phones. This was before GPS, and she talked me through directions.

You need something like this (factory prototype large tube TPI intake). Fits perfectly between the intercoolers :thumbs

Where did that intake setup come from. Or more importantly, where is it going?
