How much boost without IC, or Water Injection?

[johnl]

110 fuel - that's part of it. An old tuner I used to know, in referring to fuel, always said "increase the compression and tip the can." Turbos increase the compression and 110 or better "tips the can."

Well, its going to be street driven 99.8% of the time, so 110 fuel is out of the question.

how is 110 out of the question?

[tonyz2897]

Probably price. That stuff's a little expensive to be running around on the street.

<---Is a highschool kid that is going to be paying for his own gas and can't afford to pay $2.50 a gallon for 110 octane gas when I can pay $1.96 for 93 octane gas.

That's kind of how its out of the question for me.

I thought that might be it. I usually pay around $2.89 a gallon for it. Meh, it worth it though.

[MoparFreak]

LoL, an extra 3 lbs of boost aint worth no $0.89+ per gallon to me! I'm sure I'll be fine. And if not? Whats the worst that could happen? I'd have to rebuild a motor with stronger internals, and make it even faster!

I thought you had no money to pay for the race fuel ?

You can run 14 psi max on 91 octane on a 2.2 @ 12 deg base timing. On a 2.5 I would say back off the timing little for 14 psi on 91 octane. Unless your lucky and can get 94 octane like we do here. And Cold does make a difference. You can run a little more boost and you get a lot more power with a 15 deg C difference.

Sure you could run more boost for a while if you are a bit lucky but why take the risk if you can't afford the repairs.

Right now it's 10* F outside. But in the summer it's quite hotter.

I probably could buy 110 if I wanted to, but I can't justify that much more for an 86 T1 Turbo Z (plus I don't know where to find it). And I plan on saving up what I can to rebuild my motor anyways. I will be working this summer and am "leasing" my school orchard and have the possibility of making over $3K at the end of the summer. I'm thinking about trying to make my car a mid 13 second WaterInjected "Log" car. But that's quite AWAYS in the future.

As of now, I'll most likely leave the boost at stock levels, put a FULL 3" exhaust system on the car, update my tranny/clutch and keep it that way.
But I'm sure I'll get the craving for a little more boost...

my dad runs 25 pounds of pressure with a T-04 Garrett. no intercooler, no water injection and 36lb injectors. hes had like that since hes got it, going on 8 years and had no problems. an intercooler will greatly help you out, you'll notice the difference at high boost levels.

using NOS ? what kind of fuel ?

[Putter]

A 2.2 can spool a true T4?

Diesel? Can't see a 2.2 or especially a 2.5 TD surviving that on anything less than rce fuel.

I ran my Shadow at 14 psi, non-intercooled for a year and I never had any problems at all, but, my car has never seen a drop of fuel that wasn't 94 octane. I would say I was seriously pushing it as it was, but with crappy gas, I think no good can come of it. I've heard people talk about high boost and regular gas, and maybe their engines didn't blow, just like I'm sure that somewhere there's a Russian roulette grand champion that's had a gun in his mouth a thousand times and never found the one bullet. I just wouldn't suggest doing it. Considering you can buy a stock intercooler off any number of fine gentlemen on this forum for $50, buy a lower intercooler hose for the sake of simplicity, and you can intercool it yourself in your driveway in no time (I didn't even need anything more than a screwdriver and a drill). Take advantage of the wealth of used parts available and the relative cheapness of the parts, I spent in total (including the shipping of the parts) about $250 and an hour of my time. And thats Canadian dollars, what's that to American dollars, like 75 cents, LOL (actually the Canadian dollar is rocking right now, go Looney). The point is, you can't intercool any of the cars that the "cool kids" are driving for anywhere near that money... and if you guys actually stopped to think about the kind of crap that the import guys buy for big big money, just to get 3HP to the wheels (regardless if they tell everyone it gives them 20).
