Richard Holdener Does a supercharged 3800
- Thread starter GTPpower
- Start date
Headers were such a pain in the dick too, wild it didn’t do much at least mostly stock. I’d love to see headers added with a cam and other shit, hopefully he does test that again.
3.4 pulley ftw

Oh man I'd love to send him a modified windage tray and pan with the crank scraper welded in below cylinder 4.
One of the biggest takeaways I've seen so far is that the 3800 loves timing even on E85. I've been hearing for years from the GP guys that anything over 15* of timing has no affect especially on E85 because of the 'faster flame front'
I was able to dyno my car on power tour and saw pretty good gains by going to 18* from 15* and this just more proof of that now.
I'm also interested in seeing if the L32 is actually stronger than the L67 if he ever gets around to getting the L67 running

About 24 is max, I was able to push past 26, but it’s past MBT at that point. L32/67 really needs more compression to take full advantage of gains from e85 (with a blower anyway)
I had the S&S, they were smaller primaries, but much better design except for the collector flange. I welded in a ball and socket flange and it never leaked. I sent my headers to jet-hot, and they held up pretty wellI had coated pacesetters and they always leaked at the crossover and rusted
You can really pick up power by adding timing, especially with smaller pulleys, but you have to remember that with e85 it becomes way more likely to detonate or preignite. Either of those creates more cylinder pressure than even a huge turbo build.
With a turbo that's in it's efficiency range, you usually pick up more leaving the timing low and crank the boost.

wait, what? sorry I must have missed this one, what does it do?
Frees up power by not drowning the crank in oil?
🔧 BUILD - remember the twin engine olds?
i know of an l36 that would love to have a few of those oil mods on it :pedobear:
And the preceding 2 pages
I've always figured going compound can't be anymore restrictive than just running the supercharger alone and would make gobs more power.
In theory if he were to turn the turbo up to 20 psi and keep the same blower on the pulley this would produce around 40 psi at least on paper. The supercharger would still rob power though and create heat so obviously not ideal
Sounds like this thing is going to be making an appearance on engine masters. Can't wait to hear what Freiburger has to say about this engine, I wish they would've put this in the Rotsun instead of the 4.3l. I know Dulcich is going to crap all over this thing though

That's the problem with compounding. As you turn up the turbo, the m90 works that much harder, producing more heat with higher drive costs. That's why most of the guys that twin charge open the bypass once the turbo lights.
Would like to see the curve between this compound setup and the GT45, solo, with the same peak hp. The whole advantage seems to take advantage of the blower’s on-ness at lower rpm so let’s see a difference to determine if it’s worth it.
