Results all in all aren't too bad I think, but just want to hear what others think. As we know, track is what matter but just out of curiosity does this sound right to others?

After small random issues, final numbers were 551rwhp / 540rwtq @ 10psi with a conservative safe tune. Also guesstimating around 580rwhp at 11psi, and 640rwhp at 14psi. I plan to run the car at a solid 11psi on average since It's normal pump 93, and no meth involved. My previous numbers for h/c/i only were a best of 412rwhp, while on another dyno with nothing changed, 380rwhp. So overall it's seems like about 200rwhp increase.

Sounds like a fun setup

Do these numbers sound about right?

I think a cam change would yield more. A single pattern on a 112 is not what I would call ideal for boost. Overall looks like a solid setup tho.

Yea I could def. get more out of the cam swap. I just left it go as is for now though.

Whats your comp ratio & timing? Wandering how much the ls9 gaskets lowered your compression & if timing is real conservative. Im also not sure I buy into swapping cams. I made 704rwhp on 13lbs & my cam is definitely not considered a "BOOST" cam (236/246 612/612 110 lsa).. That was with 18 degress timing on E85.

E85 is a huge difference don't forget. I'm running normal 93. I'm not sure what my ratio and timing is actually, I know my heads were resurfaced which if anything raised my ratio honestly.

Your cam having a large exhaust split favors boost more then a single pattern even with the tight LSA. E85 makes a bit of difference as well.

Yeah, on 93 his timing is probably around the 11-15 range & his #'s are probably right for 10lbs. Fccs, do you have E85 readily available around you? You have the injectors & the pump for it, just need to add a regulator & return line.

I sort of do but not really. Closest e85 is a hour away from me. I was told by my tuner my pump and injectors wouldn't be enough though to be safe. I figure IF I were running e85 at 14psi, that should put me around 680-720 somewhere in that range.

444 before turbo 580 with tc76@7 psi. Pt76 11 psi 720 rwhp all same 11:1 stock bottom end.



Through my stock slp dual dual muffler with pt76. Na cam on 110 LSA.

8 PSI = 634 / 616
10 PSI = 694 / 680
11 PSI = 722 / 701

hella choked on that exhaust.

Damn, on pump normal 93?? I've never seen a 700rwhp on stock bottom end with normal pump gas. Meth or e85 sure, but that's damn impressive if that's pump gas. What other mods?

This was from 5 years ago https://ls1tech.com/forums/forced-in...0-12-5lbs.html
I recently got the car going again this year and put it on my buddies brand new load bearing dynojet and the recent results are on the last page. We have 91 pump gas here and I have 11:1 compression so I spray 100% methanol injection. My buddy has a stock bottom end 78mm turbo LS1 with lower compression 317 heads and hes made 748 rwhp on straight 91 octane.

Yes the exhaust kills the car but it's the quietest car around. When I open the 4" cutout I gained 4 mph in the 1/4.

Anyways FCSS I would say something is off on your car and if I had to guess it would be that comp turbo. I've never seen good results from comp turbos and from my past research they use shitty straight trim turbine wheels that don't work well on v8s.

Post up your dyno graph, I bet you can see where it runs into backpressure.

You made about 20/10 more hp/tq than my old s475 turbo at 8 psi on a stock ls1 with an ls6 intake, pump gas as well, but with that small of a window could be just different dynos

748rwhp on straight pump with no meth or e85 is insane. I have never seen one around PA that high without meth lol. I will grab dyno graph and show
