i can spin my 235/60/15's on dry pavement at a 35-40mph roll in 2nd gear. just a few more psi and ill be able to do it in 3rd at 55-whatever mph. lol.
But you didn't just add boost Bill, a free flowing exhaust (especially with your header) an intake and big four barrel, a cam, increased compression, and a ton of lightening has also helped. A slant six with these mods won't feel to lethargic at all, and then you crammed almost 70% more atmosphere into it.
If you were to use an example of just adding 10psi to an engine, Serj's would be a better example.

True; and that is the example I should have used, because it demonstrates exactly the same thing. Ask Serj how it runs, compared with before..

FAN-TASTICALLY! 3,000 happy miles and counting on this setup. 18-20mpg and that silent wooosh whenever you want to pass a car on the freeway with effortless light pedal tapping.
I had done the supersix total modification beforehand and rebuilt the entire head with new valves, seats, springs, everything, and it was kind of faster than before but Priuses were passing me up and I could do nothing about it - couldn't even catch up and I am dead serious about that. I had to mash to pedal to try to get to freeway speed even. I put a muffler back on it previously because the motor worked so hard it sounded like I was making all kinds of power but wasn't going anywhere. lol.
Brandon is out resident turbo non-believer. He's just stating how he feels about the whole thing, which is fine - but I feel like he hasn't tried it, or been near it. Someone go give him a ride with their turbo slant and show him there's a reason to do it, otherwise he won't be swayed.
It's either that, or Brandon was up really late building the fastest turbo slant block the world had ever seen. He had shelled thousands into it, and had it on the chains ready to go in the car, when suddenly DISASTER STRUCK! and lightning struck the engine hoist, and broke the chains, when the block fell and crushed his cat. He was devastated and burried the block and cat in the backyard with a tombstone of plywood that says "never forget" and swore revenge on the turbo slant. To this day he has been scouring thousands of posts to tell people that they can get 200hp out of N/A modifications, just to save them from the similar heartache that he felt.... on that fateful day...

Brandon, it seems that the important thing to consider when turbocharging a slant six (or probably ANY motor,)
is to use a cam with short duration, so the phenomenon known as "overlap" (having both valves open at the same time) will be minimized. The fact is, boost exists in the intake tract and if it is offered the opportunity to escape through an open exhaust valve, it will jump at the chance... ops: There goes your boost..So, cams not too different from a stock one work very well.
Mine is a typical "turbo" cam. It was ground by Bullet, and has 210-degrees of duration @ .050"-lift, on both intake and exhaust, with 115-degree lobe centers, and .484" lift, with stock 1.5 rockers.
That means that turbo motors, with cams like that, idle like a stocker, and have really good street manners. Gas mileage is good, too, with no mileage-killing valve train heroics going on, like a naturally-aspirated motor would likely have, in search of performance.
Hope this helps...
.........as the saying goes; power costs money; how fast do you want to go?
This surprises me. I thought the choke removed would have dropped it down to 15-17, but maybe the fact that your intake and exhaust still bolt together is helping this? and probably your exhaust is a bit hotter under the intake from turbo backpressure?I dunno, no matter though, that's great. What kind of mileage were you getting before? I bet EFI would make it even better :evil3:
...(I can't remember, did you run 2.25 exhaust and supersix distributor as well?) you had a stock engine. At best you had a stock supersix.
