It's peaking around where I would expect for that cam. The curve is smooth so doesn't look like any misfire issues. A boost leak is possible but it would be small as having a pipe come off would not result in that kind of power.
Honestly the power curve looks nice. Increasing boost should move the midrange up significantly but you may not pick up the same amount up top. The comment regarding spring seat pressure is going to be important if you are increasing boost.
I saw a soft amount of valve float when I went from 15 to around 19lbs. Mid range picked up big time since it saw more boost earlier but went soft up top with nearly the same peak numbers.
New valve springs, same cam and minor valvetrain changes netted me another 70 or so at the tire.

I figured I give an update of my new setup.
- E85
-OBX longtube headers. 3.5 collectors, stepped 13/4 to 1 7/8 primaries.
- bumped compression up to 9:8:1 (wanted to go higher but I'll run this.)
-got a 4 inch blower pulley. Looking for 20 psi or little over that.
-redesigning my loonies double walbro in tank feed setup.
- walbro 255 lph pump and walbro 465lph pump in tank pumps.
-3 inch true dual exhaust, X pipe under axle with C6 Corvette Corsa sport mufflers
-Manley Nextek valve springs with retainers and locks.
- dual methanol nozzles.
-Diamond .040 over bkower pistons
- Bosch 160lb injectors high impedance.
I took the heads to Lloyd and we found out that the old springs were in fact having valve float issues. I talked with my tuner and he said gains of 100 rwhp was possible just from switching 93 to E85. I'm going to shoot low but I think it will put down 850 rwhp this time around. What do yall think?Last edited by 96famaro; 05-04-2016 at 02:01 PM.

Willing to share how you are modding the Lonnies twin pumps to the bigger units? Did you already do fuel lines? Switching to E85 and pushing more timing should net some nice gains. What were you putting down before? Maybe you already posted that info.
Keep us posted.

its going to be fun to drive.
I don't mind it one bit. I already installed my fuel tank back in the car with the way Lonnie left it, so I have to get it back out again when I'm ready to do it. This was just one of those last minute decision. I feel that it has flow restriction on the T- fitting. I'll share how i go about doing it my way. Real reason this idea came up is when i ran across one of Squash Performance dual pumps for my CTSV setup and got me thinking.... I modified my fuel rails. Added a larger diameter feed tube and added an additional bridge tube. -8An feed line, -6AN return. was putting down 700rwhp.
yea i figured id step it up. I don't want to be left behind by the new gen LT1orLT4 which seem to make ridiculous power with little proper tweaking.Last edited by 96famaro; 05-05-2016 at 12:25 AM.

Forgot to mention that I believe my electrical might have not been up to par as well. It might have been ok but I like to know that it wasn't just borderline. I ran a 2/0 gauge power cable from rear to front of car and two 2guage ground wires to rear chassis and 2 gauge ground cable, engine block to chassis. And a 2guage alternator power cable to front positive distribution point. I also upgraded the alternator to a Cadillac Escalade 145amp. I also moved the Racetronix dual fuel pump wiring to where the positive connectors are connected straight to the alternator output rather than putting it at the positive distribution point.
