Great numbers...What is your compression ratio? I see your heads are the TFS 35s with 70cc chambers...are those flat top pistons? What dish/valve relief if not?
Thanks

my best pass to date in the 1/8th on motor is 7.41@96 with a 1.71 short time..
made 1 1/8 pass on the bottle... 7.14@101 with a 1.85 short
and made 2 1/4 passes on bottle 11.24@128 with a 1.86 short
car weight in a 4k lbs with me in it.. and i was on a 335/35/17 hoosier drag radial....
but the 1/4 nitrous passes were at 13.5 a/f and only 10 degrees total of timing... so i need to work out my fueling issues.. but it does back half like crazy

CR is 11.25 and the pistons are 3cc pistons. Motor is built for spray, spec'd for a 250 shot with current cam. Which may or may not happen, lol. I gotta get used to this setup first. Went from H/C/I w/ 436/382 to this. I ran a best of 7.71 @ 92 w/60' of 1.73 1/8 with my previous setup.

Glad I found this! I am wanting to build a base 550whp motor then add a twin turbo setup for an easy extra 300+ hp. This thread will give me some great ideas for a base 550 motor.

Keep them coming!

It will be hard to get a 550 NA motor that has low enough compression to put much boost on it. You would be better off going for mid 400s and 9.5:1 compression and then you can push 10psi all day. Just throwing that out there.

I don't mind higher Comp; just means more power at lower boost. Mix in a little Meth Injection and all is good
Car put down 517/489 consistently over 3-5 runs at 88 degrees F, 30.16 BP, and 51% Humidity with SAE CF 1.00
I ended up staying NA and used PRC 2.5 LS6 heads milled 1cc to clean them and .040 cometics. Pistons are -10cc. Also went with ported FAST 90. I still need to port the throttle body but I am fairly happy with the runs.

I have two head options (because I have both in my garage).
First a set of Stage III Patriot LQ9 heads.
The other option is AFR 205, milled to 59cc.
My cam is a Comp XER 244/248 612/615 114+4.
Kooks 1 3/4 with 3" DMH cutouts and ZO6 Ti exhaust
Mizeire EWP
TPIS ported LS6 with Billet TPIS 85mm oval TB
I think that is all that matters for power production?
Any suggestions on milling the Patriot heads for NA application? Any issues with PTVC for the AFR @ 59cc? Head gasket size for max efficiency?
Since my last post in july, I swapped the 243s and Fast 92int and 1 3/4 LTs for CNC LS3 heads, Ported LS3 int, pulley and 1 7/8 Lts. I put down 495/470. I thought maybe another 10/15 hp higher. Going to go to another tunner.
That is a great 60'...I bet it feels great coming out of the hole...
Especially considering I went from a 2.0 to a 1.59 60' it def feels great! I can't wait to get some less used up tires and take out some weight to see if I can't get it even lower
