Hey, newbie here. I just got my YSi (Thanks Ricky @ Vortech, removed a Y-trim. So far i like it but my current setup would not allow me to take full advantafe of the YSi.
Only Dynoed 645hp/696 tq through powerglide with my 302. My mass air was not correctly calibrated for the YSi ( was only cal. for a S-Trim ) and was maxed out between 3000-4000rpm. We were moving alot of air. This in turn showed my 72lb injectors were at 100% duty cycle. A/F was 12.0 to 12.2 I was running a 77/27 cog setup. At 6800rpm i saw 27 psi. Air charger temps after my spearco in dash were only 66 degrees.
My new FAST sequential is on the way and soon 96lb injectors. I am going to try the YSi and the 302 again before i put in my 345 with new cam and heads.
The hydraulic cam i am currnetly running is not very good for the Vic Jr. heads and blower.
The new TEA cnc'd heads and solid roller cam along with the 345 should make a crap load more of power. Not to mention the FAST sequential.
Just wanted to share some info.
