Wonder what he did for fueling solution? I know some are on the horizon and or starting to come out. But just recently power like that surpassed even modified lt4 system. I bet he also at least re gapped the rings. Stock they are way too tight for that much boost

The intake he is running might I think. Wonder what all is involved to run the port with it. Looks like a nice manifold but I think it’s 2 grand plus alone.
SS is done at 500 ish rwhp on E85 stock system. Little bit more with extra fuel love cam. Around 600 on 93..
been considering fi more lately. Mainly since I’ve read all the lt1 really needs to stay reliable near 1000 hp is re gapped rings. I’ve done the heads cam thing a few times now and might try something different idk. May even do ported heads and a large blower cam. Stay na with that for a bit. Then get a sc. more power with lessboost is a bonus to me. Much more reliable

Yeah I wasn’t aware. Started reading up on 5.3 motors making near that with re gapped rings. Then came across someone at Procharger who plans on just re gapping his 6gen. Thing is most will put in a little better piston and or rods when it’s already apart to hit the 1500 hp and or be more reliable.
i can’t imagine needing more than 8-900 hp at this point so may just re gap if I go fi

Also want to drop a few more tenths with bolt ons with more mods and a converter. A 4c isn’t a good choice for a whipple I’ve heard. But will work well with a Centri and na
but then will a ported msd work very well with a Centri as far as holding boost? I can also recoup money selling my ported msd if I go whipple
i guess a re stall is usually only a few hundred right?
hmmm... idk

yeah it sucks
from what I’ve gathered the pistons aren’t that bad. Most just do the Pistons with the rings while it’s apart for extra insurance. The guy from Procharger I spoke to said the stock pistons with re gap would be good for 8-900 possibly more. Just aftermarket Pistons around 1000. Need rods approaching 1500 range
theres a few making over 700 completely SBE but the consensus is that 7-750 is the max depending on boost. Reliably that is. Many may push it and be fine but safe recommend limit is about 750 SBE

Without an increased fuel lobe cam it’s right around 500 with E85. 550-580 with cam lobe I believe

plenty of high horsepower SBE LT1's living under boost. most that have blown up are running lean up top because the fuel system is not up to par. with direct injection the timing window for spraying fuel is very narrow. when the injector pulse widths increase and get above 6ms bad things can happen fast. LT1 does not need E85 until 700whp that is where the octane wall lies. LT4 fuel parts and a bigger lobe cam will support 660-720whp on E60.
Jessica Joy has been making 850whp on the SBE for 24k miles with over 200 1/4 mile passes. She just finally broke the rear end this spring.

i would do E85 regardless for the extra cooling, more power with less boost and I’m not gonna pay 4 bucks a gallon for 93 gas when I can get E85 for 1.80-2.50 typically. Even starting out if I’m just looking for 600 range I want E85

i would not be suprised to see a stock terbo accord modded to make 400-500hp. man you know your car can do whatever anyone else does on motor, but its a big waste of money and time. even a small amount of boost is available any time you need it. just saying.
BTW coyote rings for 2011 and 2012 are crazy tight. a lot of all motor cars butted rings and popped number 8. forced induction cars almost never butted rings. flame temps are lower for forced induction with a fat air-fuel. it not the power level that butts rings, its combustion temps and running it for a long time at WOT.

it's ok like you are saying to stay all motor, but like others who are making your power, they hate to lose. think of all of the terbo cars from the factory now. all of the manufacturers are being forced to build small engines with a terbo. even a porsche 911 carrera is turbocharged. IMO nitrous is a easy answer for the track.
