nope i have another timing table, i believe 23psi 17deg

its out of turbine so i had to push, but it is flying with that tuneup

How did you identify it was out of turbine? Do you monitor back pressure? Or is it the amount of gain you saw from adding additional boost? Amazing.

quik67

Amazing !!!
You always make this **** look so easy , ha ha!

What did you do to the Th400 to make it live at that power level?
I know you said home built , but was it cheap Denmah style too?

Nice job Matt is that still the ls1 intake and 80mm billet?

LJMSJohn

Still on the LS1 intake... but it has a Billet 84 on it right now.

Imagine what stock L92 heads and a Victor Jr with Accufab 4BBL throttle body would do!

yeah just over 900whp it struggles with hp per lb of boost

down low its like 30-40whp per psi easily and up top its under 10hp per psi

so its something, i think its the turbine since its 403 cubes on a 96 turbine
i would be willing to bet the gt55 94/103 or whatever it is would make much more per psi and more top end

but the car is already exceeding expectation everytime we try, and its reliable as all hell, same spark plugs in it from the first time i dyno tuned it.

unsure if this would help really since i think the turbine is running out.

denmah

unsure what was all done, i just know marks buddy built the trans.

i dont think there is anything exotic done at all, just RMVB and brake
pressure mods i would assume but other than that.

LJMSJohn

Probably slow the car down and get the compressor wheel all outta whack.

Lets hope not since I just ordered one from you for a 408 with L92 heads on it.

LJMSJohn

Your setup had the L92's accounted for. Don't worry...

Since we are talking about the s484 running out of turbine with the 96mm. Any update on Jose making the 100mm wheel for this thing?

i believe the next step is their gt55, wich is like 94/102 for the entry level turbo size

The heads would lift and the intake would flow less than an LS1?

turbo6man

iTrader: (5)

That makes sense. It sure would be an awesome test bed car for that wheel though. Is the GT55 alot bigger? Do you have room?

The GT55 is bigger, but not that much bigger. I put a 91mm GT55 in my car this weekend where an S480 had been and while it took some massaging, it went into the same spot.

Gt55 is a 102/112 turbine
