i ran 11.3 with CJ, Headers, 93 tune and 3.31 gears you should be in the 10.9's easy

@@na4valve I was only able to make 2 dyno pulls because the dyno shop kinda screwed me on time, they double booked my appointment and the guy that arrived before me took up the whole day, I only had 2 hours. I received 1 tune revision (base pull and then revision pull) and it made 600whp on pump E with only 25 degrees of timing. It picked up 20whp from base pull with just 1 degree, so I think it would have made 630-640whp on pump e85. The engine ended up spinning all the main bearings a couple days later so never got to really find out. New combo should be done soon and it will make a lot more power. Also, knowing what I know now, Mike doesn’t have 17:1 compression, the most you can get out of these is a hair over 14:1 due to the physical size of the cylinder vs combustion chamber volume. His car still made stupid power which just shows how good of a builder RGR is.

17:1 is not particularly difficult to get out of a 3.900” stroker combo Voodoo heads should have a ~57cc combustion chamber volume, this doesn’t include area added by the head gasket. Assuming 3.700”x3.900” bore/stroke, 5.85” rods, 1.129” compression height pistons with .200” down top ring (N/A ideal), 3.71” x .032” head gaskets (shelf stock Cometic item), 8.937” deck height with .008” piston to deck clearance we arrive at: 0cc (flat tops) - 11.61:1 5cc dome - 12.49:1 10cc dome - 13.54:1 15cc dome - 14.8:1 20cc dome - 16.34:1 22cc dome - 17.06:1 10-15cc domes should be relatively easy to achieve good dome dimensions that won’t interfere with flame propagation much with a pent roof chamber and a central spark plug on 3.700” bore. 15cc+ would require a chamber mold and a good piston designer but still totally doable, IMO. Dome size could also be reduced through cylinder head and/or block milling, increased compression height or a thinner head gasket.

@@g8r5oh10 what is different with the new combo? I am currently in the process of gathering parts for an NA 4.6 build.

Damn, what’s yours run lol

Yeah if you’re ghey

@@g8r5oh10 you know nothing about drag racing bro

Well stay tuned because this engine had some issues but the new one will be way mo betta

@@g8r5oh10 can't wait to see it in action

@@g8r5oh10 is it also from rpg?

Do you have social media looking to connect with you on a few things?

@@g8r5oh10what kind of issues?

Hopefully starting assembly soon. The stroker in the video got hurt from a loss in oil pressure after 500 miles so it’s been getting fixed and I’m building another stroker that will have more compression. Just waiting on CP to finish the pistons, they were supposed to start machining them either last week or the week before.

@g8r5oh10 that sucks but seems a work in progress. It's gonna be badass that's for sure. Unique build man. Are you keeping it N/A?

@@dylan123perreault primarily going to stay NA but I may add a little extra ring gap in case I want to spray it, I’ve been thinking about maybe throwing 200 hp at it.

This video was of the old combo that ended up spinning some main bearings. The new combo will still be a 5.5L with ported voodoo heads, 600” lift cams, competition ported CJ manifold with custom plenum but compression will be a bit higher, probably 15.5:1ish

@@g8r5oh10 wow! Super curious what kind of power it makes. What are you hoping for power wise and what fuel are you going to run?

@@coryemerson9225 it’s going run on e85 for now and should make mid 600’s to the wheels. The engine in the video made right at 600 with basically no tuning.

@@g8r5oh10 650rwhp NA on E85 is so badass! Car should go well into 9s at over 140. What kind of power was it making when you went 10.1@134?

Man that’s nuts… he knows his shit with the 4.6/5.4 so kinda crazy to me. Seems many mod/coyote builders are cutting some corners lately.

This engine lost oil pressure earlier in the year and I lost motivation to work on it for a while. Finally got the itch to work on it again and all the stuff has been sent off to RPG for repair and I’m building another engine that will be the primary engine. Going a little higher on the compression, waiting for diamond to finish machining the pistons then the rotating assembly can be balanced. Hopefully early 2024 it will be running.

Can't wait to see it in action

@@g8r5oh10 What was the reason for oil pressure loss?

Wdym

It’s not a speaker he stated the VCT was not compatible with the cams so it’s locked out

… no it doesn’t 😂

Yeah sorry for the lack of updates. The short block lost oil pressure and hurt the crank and block very badly. RPG is going to get it fixed up but I’m building another 5.5L that will be higher compression. I’m waiting on CP to finish the pistons and then MPR has to balance the new crankshaft. I’m hoping to begin assembly in January.

What caused the loss of oil pressure?

@@iamarclover123 ring lands coming apart or oil pump coming apart.

​@g8r5oh10 MPR is building the other 5.5L? Cant wait to see you finish man. I saw your 321 build video against all those boosted cars you beat. I could only imagine how many feelings you'll hurt with the new motor 😂

@@chriscooper8210 MPR is doing the machine work and they specs the new pistons for me. I am doing the blueprinting and assembly. That 321 engine ran good, I feel like I should have stuck with it more and tried to squeeze more from it before screwing around with different fuels and eventually hurting the piston.

I ran a 28” tire and turned 86-8700 rpm so it could go 140+ in 4th. It did almost 135 in the 1/4 and I passed the traps in 4th

You’re welcome, any time 👍

Yes pump e85 for now

Going to be a while unfortunately. Down for repairs and I honestly don’t feel like working on it and haven’t felt like working on it since I took it down in March.

@@g8r5oh10damn man I wanna build a 5.5 and your the only guy I can find videos on it
