17 Psi Of Boost

Ok with the boost bypass i have 9and a half lbs of bost and it hits 10 when it shifts so ill have 13 and a half with the 4# pulley. If i undo the bypass and get the 6# pulley ill have an even 14. WHAT SHOULD I DO

FWIW I'm running a 6lb lower, JLP CAI, Predator and STOCK spark plugs. Admittedly, probably with colder plugs, I could run two more degrees timing.:rockon:

Sure. Why?
Why, because you are playing with fire scarecrow..
By that I mean, you are risking things by not changing plugs.
I am not saying that you can't do it. I am just saying why not play it safe and do things right and not have to worry about breaking. I have been there done that.. not fun or cheap..

Actually, more boost means LESS timing. Or detonaion will occur.
With the proper tune, you can run stock plugs..
I would just go for the 6# pulley.... I ran a 6# / 2.7upper for the longest time on my stock block with no problems.. before I switched to the built motor I ran a 8# lower / 2.8upper for a while just to see what she'd do...
Stock motor came out of hte truck running when I put the built motor in...

Dale,
What I meant was timing was going to be added to the list of things to be changed. After reading it, its not exactly what I said in the post. But it was what I meant.
And also, I have seen personally stock motors break with 10 miles on them on a stock tune. Stock rods suck bottom line. I wouldn't trust them with any more than 14 psi. That's the point I have been trying to make.

I've been running 14psi, Bassani full exhaust and CAI with Predator tune and 21deg timing. Truck made 405rwhp and 495rwtq on the stock plugs. It only has 3800 miles. It must be because the DSG's are the fastest!!!:-D
You were lucky Dale. Your motor is the exception, not the norm.
There's always an exception. For example I had a 97 GT that made 450 rwhp and 452rwtq with 19psi from a D-1SC on a completely stock longblock (non PI). It ran/raced for 2years, and still ran when I pulled it out. My friend's blew up after 3hrs of 10psi:shrug:

First of all, if you run conservative enough on timing, you don't have to change plugs. Secondly, staying out of detonation is the key point, which is what I believe I am doing. If I change plugs, I believe I could go with more timing. I also have a good ear for detonation, as I have been into the hobby of racing for years. Besides, JLP told me that these rods are hit-or-miss anyway, so if that's the case, there is no 100% sure way of something not happening. We can only hope with these motors. :rockon:

I ran a 6 lower and a 2.66 upper for about a year before I swapped mine too.
I wouldn't mess with the 8. The Eaton is pretty much done after an extra 4 psi, but with the 6 lower, you will gain some bottom end power, and loose some top end power.
A good tune is the key, and with that said, 17 psi, with a good tune, the right driver, and some good gas would be fine.
I have none of the above:lol:
