Hey guys, and maybe even girls. I have an 85 GN that i have modded an ok amount and was wondering what to expect for times from it, and maybe even horse. I know it will just be a guesstimate but i was just curious. It pulls hard but i smoked the clutches in my tranny this summer and never got to the track after it was fixed, here in WI the tracks will still be close for a while. The mods are as listed.

1985 Buick Grand National: 70,000 miles.

-21 pounds of boost on xylene/110 mix. absolutely no knock
-complete engine back,stainless ATR exhaust, everything in engine compartment ceramic coated, 2 1/2" DP, No Cat
-TA-33C turbo
-Ported/ polished heads (Iron) and intake.
-1.77 intake/1.50 exhaust stainless valves.
-heavy valve springs and strengthened retainers.
-Poston 110t cam, chromemoly pushrods.
- 42.5# injectors, Eric Marshal tuned chip.
- Ported throttle body
- 4" cold air intake (Mandrel bent aluminum pipeing), 8" K&n filter

I think i posted all the things i did that affect performance, i have all other mods done to be on the safe side, Complete ARP studs, driveshaft loop ext.

Any comments apreciated!!

I agree with the previous post. A friend of ours ran low 13's with less of a set up then you have with good tires.
 
Thanks guys, i had and idea of somewere around there but wanted a more educated guesses than one, now i will have something to look forward to this summer.
Thanks,Dan
 
well i would think u would trap a bit more than me tuned properly like 110 and u can see my times in sig so i would say dr's and some 1230's cant see why not all i did was wach knock adn change fp and psi wich is no real way to tune ecm was stock no chip and so timing was the same u shoud ge low 12'sunlessmy car is just different??
 
if u dont get close to my times then get andintercooler or some meth inj.? just my 2 cents, but ur car wil hual ass with either
 
Im working on making an intercooler setup, and was going to buy a meth kit but backed into one of my bros friend's cars last night with my truck (Damn Tint and little cars :(....)and now have to pay for that.

Thanks, Dan
 
just to give u some more motivation my car was not even tuned it just hooked good and ur car has more in it then mine does should move well keep us informed
