I just put a d1sc procharger on my car and I was wondering what kind of power is normal for me.

I have ported 243 heads with a 232/236 595/ 601 on a 112+2 xer lobe.

I am running the twin intercoolers with a 4.25 pulley on the blower.


The dyno I ran on is a Mustang dyno, but is notorious for producing lower numbers. On motor before the install I made 356 hp.

I made the runs with the converter unlocked with the 12-bolt. Timing is at 19 degrees and my AFR was 12.0.

The car made 440 Hp and 400 torque. This was with 5.5 lbs of boost


I was just wondering If this was normal or is it a little under powered for what I have. I know the cam is not very good for boost, but I didn't know how much difference that would make.


thanks

 

how big is the converter? yes it's a mustang, but you do have an auto, 12 bolt, etc. I'd be happy. whats the chance of taking it somewhere else?

 

I think those numbers look fine considering it's a mustang dyno, you're a stalled auto, and you're only pushing 5.5 psi.

 

Those are good numners with Mustang dyno Unlocked Converter and 12bolt and such low boost take it to the track.

I dont think your cam is good for forced induction.

 

I am not really concerned with dyno numbers, but I didn't know what I should be doing. I ran the other day at a short track and i ran a 6.90 which would be a 7.30 on a full 1/8 mile track. 60' times were in the mid 1.6 range.

I have a Vig 3600 multi disk converter

I didn't log my runs, but I would imagine that my IAT's were not great because it was hot and muggy outside.


I am really loving the boost so far. I never had to fool with the bottle pressure or anything, I just cranked the car and made a pass. I am going to swap over to a boost cam and put a smaller pulley on the blower.

 

Turn the timing up to 22 degrees.

 

We found out that I have had a problem with the boost all along. I had a little hole in a pipe and I needed some t-bolt clamps. I now make almost eight pounds with the same pulley. I just made sure the tune was safe for me now.

I should go to the dyno maybe next week

 

Those boost levels added to the NA Cam would require higher than normal timing for FI.

 

Can't wait to see the new numbers now that you've figured out the issue. Keep us posted.

 

Yeah, I was thinking that you had a bvoost problem. I had thought it might have been cam related, but now that you found the problem you should put out a nasty number!
