What kind of boost numbers out there?
Stock engine/Modified
Vortech/ATI
It doesn't matter what you got just post some psi levels,if possible include your idea of off idle/intial boost and max boost at your given rpm levels. Dyno numbers welcomed.

12lbs of hot air. Intercooler coming soon.

 

Is that on pump gas?
How's your timing inital and overall?
Sounds good

 

Sunoco 94
Base Timing 8 deg. overall 22 with boost retard
Thanks, soon it will be intercooled to allow full timing.

 

I am able to run 22* total with 16 lbs on 92 octane with about 3* of knock at shifts.I due run less combustion compression at around 8 to 1.This is with my buick by the way.

 

D1SC
3-core intercooler
Water/Alcohol Injection
8.7:1 C.R.
38 degrees total advance
NO boost retard

See sig for more details.

 

hell even though not what you wanted I will chip in
running 12psi creeping to 15 on 9.0 compression. running 92 octane

hp G-tech ( yeah I kno wthey are not the best) at 295

 

Willie,

What have you done to lower your compression to 8.7:1??

Just wondering

Regards

Robert

 

What have you done to lower your compression to 8.7:1??

TRW forged flat top pistons with valve reliefs,
0.051" compressed thickness GM composite head gaskets,
58cc Corvette aluminum heads but....


Most of this has all changed in the last month.

I'm now running 0.041" gaskets and
56cc AFR heads for a 9.22:1 C.R.

Wille how much installation time/effort did the blower cost you?
38* is alot what kind of trigger does your alcohol system have and what is turn on point?

 

Wille how much installation time/effort did the blower cost you?

Installation Time:
Well, I took my time. The instructions suck. About three days. But if I had to do it all over having done it before, it would take about 1/2 day. The kit generally comes with an FMU and a secondary in-line fuel pump. I did not purchase the FMU (so no installation time here). I use Carroll's Superfueler instead. Also, I already had an in-line Vortech fuel pump so no installation time here either.

Cost:
The D1SC with three core intercooler costs anywhere from $3300 to $3800, depending on where you get it from and how many "options" you elect (like a polished blower, etc.).


38* is alot

Yes, it is. But keep in mind that you make more power (on any engine) with as advanced a timing you can run as long as you don't detonate (general rule of thumb). I can run mine at 38 degrees with zero knock retard throughout the rpm range at WOT, so why mess with a good thing?


what kind of trigger does your alcohol system have and what is turn on point?

I use a 30/70 mix of distilled water to denatured alcohol at 100-psig through a 0.015" nozzle. The water/alcohol is injected just in front of the throttle body. It is turned on by a Hobbs switch which presently is set at 3-psig boost.

Wille you been tinkering for a while on your ride. Because you know your stuff.
I 've got 2 friends that use the alky kit,and set it around 14 psi with the ability to run 22/23 psi of boost on 93 octane.
I need new motor mounts because of the false knock I get.
Alright last question to wille how much do you have invested in the engine/go fast parts?

 

D1sc @10#'s boost upping to 12#'s this spring
3-core intercooler
stock 9.3:1 comp
MSD boost retard set at 0
stock 6 degree timing
24# injectors
ATI FMU and in-pump
