the car is pulling insane.... feels very very close to how it feels on meth. the difference between this and my meth tune is with the meth is the timing is much more advanced so spool is alot better... im hitting 28 psi around 3400 rpm's versus 2900.

cheers!

 

This practice of 28psi on stock turbo on 93 octane is not a recommended idea, nor is it a responsible thing to post about.

Next thing you know, some newbies will try it and end up spinning a rod bearing.

I am curious how boost is being measured as it appears the gauge is reading high.

Lastly if you are able to "actually" hit 28psi in 3rd, a 4th gear pull will have loading drive boost over 30psi, which is just plain stupid to do on pump.

 

im using a stewart warner gauge and greddy profect b 2

and yes in 4th i do boost more.... but because of the hard core tapering... driving from gears 1-4 hard the most boost seen is 26 after 5500 rpm's. if i had a better bov it may hold it better.


i also dont plan on running this map all the time. when i go out racing or just for fun every now and then.

 

It's very unwise, especially because you're having to do rich AFRs with low timing, which equals high EGTs. High EGTs in the top of 4th at 28psi = kaboom.

You're also a bit confused on the "hard core tapering." Of course you don't see more than 26psi when going hard through the gears, because you enter the next gear at a higher rpm where the boost is already tapered. If you roll into boost in 4th gear, it will hit 30psi, then you'll probably get some knock along with your high EGTs. This is a recipe for disaster.

 

i agree with what your saying... but like i said for quick pass's not lots of aggresive daily driving. its an alternative to running methanol...

 

Not really. One method has the proper fuel and the other does not.

 

If you guys think 28psi on stock turbo is bad, look at this fool......he...well his boost gauge says hes running 30+psi, with "no meth or NOS, only 93 octane"

click on vid in first post

 

well thats what got me started... but i cant see any point to running that much boost.. im sure i can get a little more out of the turbo... but im just looking for a little more than a regular 93 tune.


im sure my cars making near his power now.... only reason he's so god damn fast is because all that wieght he dropped is equivelent to gaining around 50whp

cheers!

 

There is more power to be made in ignition timing than boost. You are just blowing hot air and having to reduce your ignition timing. Its great that you appear to have low to no knock, however to say what? That you run 28psi on pump? Is that the goal, because it is not optimum for performance. I learned this long ago.

 

How about trying to reduce the boost, lean out the AFR and keep timing the same and tell us if you made more power or less power using DLL?

 

i know your the professional.... but it definetly feels alot stronger...

im going to keep messing with it... try all different variations.

 

Now how does this apply to a 2.3L application? If you are saying that its unwise to run 28psi on a stock turbo with a stock block, what would be a safe thing to run on a 2.3L built block + 93 pump + stock injectors??

 

No.

 

running that high of boost will get the EGT's very high like Warr said, which is sooo not good. Either way you look at it, if you run lower boost with more ignition timing or a good tune in general your sure to make good power in a lot safer manner. This high boost on 93 kick that people are on is going to cause a lot of engine distruction, which is good for the vendors i guess.....throw your money at them for a new block, they like that kind of stuff, lol!

 

lol great .. now we got two guys doing it. Let's see who blows his engine first.

seriously man, every noob on this forum knows boosting that high on pump alone is gona lead to a destroyed engine. are you trying to prove that point? if so keep doing it and g.luck!
