Why do we need alky?

[Ty's 93-TYPHOON]

Re: Why do we need alky?

It comes down to your set-up. They are on average ten years newer, than ours. My buddies 1993 Supra has reached its limits. He has to go way bigger or go home. He now is in the middle of dealing with snow-performance on a kit. He wants more without total rebuild again. He has built everything up but the bottom end. so imports use it too.

A small monkey wrench for ya. A stock turbo @15psi runs stock slow. But the big dogs on this site are smoking all four tires @15psi (bigger turbo). Now remember @?psi only matters if you both have the same turbo.

Alky makes our trucks run safer. Need i say more :tup:

i've had a number of other turbo cars before the ty, and never had alky on any of them, eaven hevily modified, running 23lbs on my audi s4, i never had a problem with detonation or knock. i think it i just that they are more effiecient and run cooler. the spark control is way more advanced. it self corrected the spark advance even after i would tune it. that and with smaller engines, the same psi does not nearly equal the same volume

Ask him again in 3mos if he's still running at all let along high boost. When people don't monitor anything they just keep turning up the knob and eventually... pop!

bingo

Re: Why do we need alky?

we also have a much bigger stock turbo than most other cars. Plus we all put these stupidly big turbos on our trucks compared to the other guys upgrading to almost where we start out.

Put a bigger turbo....like gt35r or any 60 series turbo on any of the aforementioned cars....and i bet they're no longer able to run 25+psi w/o some help.

and another winner

Yup. Boost greed kills.

Half of those guys don't even know detonation exists, much less that it's killing their motor.

But as others have said, makes a big difference when you design things knowing that they'll run boosted. TRIAD/PAS took GM shelf heads, made an intake fit, used a shelf cam, and turboed it. Given what they had to deal with, the short development timeframe, and less-than-open GM internal culture, I think it ain't all that bad.

Imagine an Aluminum version of a vortec head, with an intake to match, and a cam more suited to a high boost application. It's a shame they didn't get to the 94-95 MY in development- I think we would have a much more stable platform.

Re: Why do we need alky?

Ask any fast import how much they pay per gallon of race gas. Almost guaranteed they are paying $10/gal plus.

As far as engine differences, the HUGE differences are our LARGE bore (4.00") compared to their small bores, our 2 valve head compared to their 4 valve (and their spark plug is right in the center), their aluminum head and block compared to our cast iron, and most importantly - THEIR HIGH RPM COMPARED TO OUR STUMP PULLING 4400 RPM!

When you do higher RPM heads & cam upgrades, you can run more boost on pump gas than you could with the stock 4400 RPM heads & cam!

Try comparing our torque to that of an import sometime! Then the tables will really turn.

PS: One other thing to keep in mind is static compression. The DSM 4G63 had either 7.5 or 7.8:1 compression!! Incredibly low.

Stage 3 srt4's come with a computer that will have 2-3 settings.

One of which being the high boost setting, when you do not have the octane needed for that setting it will automatically bump you out of it and put you back into low boost.

My old man has a stage 3 srt4 with a wet kit made some damn good power on the dyno but doesn't go anywhere in the 1/4 lol

AWD>FWD

catch a light and watch him spin

Re: Why do we need alky?

more timing, higher boost, pump gas, ZERO KNOCK. that's why I use it :tup:

The stage 3 is also a turbo swap.

You guys need to check out the latest issue of Hot Rod magazine... they've got an awesome article interviewing the design team of the new Vette SC motor... it tells you exactly what an OEM does in today's world when building a boosted motor... lots of cool info in the article. One of my favorites is the guy in charge of the heads talking about the heads slightly bouncing off of the block under high boost/RPM conditions - the reason they went with 7-layer head gaskets.
