Should be interesting. 427 LSX, PRC 285 heads, 232/246 cam. Ysi is being spun to max. Made 917rwhp on a 3.1"/7.25" combo last year, now has a 2.75/8" combo along with a bunch of other stuff. Lighter clutch, light driveshaft, etc. It will be interesting.

What's the goal?

 

[Unreal]

Steady AFR really. Numbers aren't really important as much as getting the tune good. Too hard to street tune it.

Any gains over last time would be nice, so 918+. Swapping to 2" headers and a 4" intake over the next month or two so it isn't like these are the final numbers. I just want to see what it is doing now. Friend did 1012rwhp on a novi 2200 on a 416 a few weeks ago so would be nice to beat him just to rub it in.

I bet 1055. What do you rev that thing to?

 

[Competitive Driver]

With that engine combo I don't think you'll have a problem beating the 1012 number. What's the compression ratio on that motor?

 

[Unreal]

7200 or so.

9.7:1 pistons. It is all 6 bolt block/heads. All coated. Motor shouldn't have an issue. I got the fuel system. If anything octane will hold me back as I'm just going to run 91 for now. If I throw vp109 or some good gas I bet it would make sick power.

Who knows. I'm hoping for ~1050 but you never know. Belt might not like it, or something else. Seems I never get clean dyno runs.

Are you running a flip drive type system? The big restriction is on the intake side going into the YSI. Open that up and you see huge gains there.

Damn this is some badass ****ing 91 Octane you have!!!

 

[HattoriHanzo]

Post some vids up after, I want to hear that thing scream

 

[SYCHO]

Damn this is some badass ****ing 91 Octane you have!!!

One thing to keep in mind is a 4.125 bore @ 9.7:1 is gonna respond to boost like a 3.9 bore @ 9.2:1 maybe even 9.1:1. I can see running out of octane around 16-18 psi.

This things gonna be a monster

 

[Unreal]

Hard to say on the octane part since it has dual meth nozzles dumping a ton of meth. Not straight 91. Another local made 1026 on a Camaro on 91 and meth on 12 degrees.

Yes it has a direct drive belt setup.

I'll dyno it with the intake on and once the tune is good I'll pull the inlet off the blower. Last time it made 958 no inlet. Solid 40rwhp gain. I got a short radiator with a 4" inlet pipe on the way along with 2" headers for later.

 

[Unreal]

Raining pretty bad so rescheduling for a later time.

16 degrees ~21psi no knock, running hard. Meth controller set at 5. AFR low 10s on meth.

 

[CruseMissle]

Nice I've noticed mine 10.4 with meth spraying knob set at 6.

 

[Unreal]

Single or dual nozzle? I have dual. It will make whatever the little YSi can make. Next month I'll swap headers/etc and see if I can get a bit more but somewhere between 990-1050 is realistic.

 

[CruseMissle]

Duel meth ysi setup also

Unreal sauce in the tank = 1400 moon unicorns to the wheels

Do it, i promise.
