Re: 401 twin turbo new track best
Winter is about here so taking car off the street i guess. Weighed it yesterday in full trim and its heavy lol
3814 with me in it.
1095 lf. 996 rf
881 lr. 845 rr
Heavy split there. Need to focus on moving things around and cutting weight.
So day of the 8.2's runs with the bullhorn exhaust it was likely down 70-75 lbs.
I'd like to be 3600 with me or better. Shouldnt be to hard with aluminum work, skinnies and maybe lexan hatch lol

Orr, what shocks and struts are you running? I'm getting ready to order some double adjustable shocks curious what struts you have.

Re: 401 twin turbo new track best
Lol i dont have anything good at the moment. I have old tokico illumina 5 adjustment shocks and struts. I am happy that these basic shocks worked so well.
I plan to go strange doubles in the rear and strange mustang singles up front after i cut spindle down for them

Re: 401 twin turbo new track best
Lol that's sweet you've been low 8's on a street shock. I am also going to get the strange doubles and was looking at doing the mustang strut or some lakewood 90/10s haven't made up my mind there. I think ogie with the procharged T/A has been 7's with lakewood 70/30s!

Re: 401 twin turbo new track best
thanks, i was trying to figure out where i wanted to put mine. i set it up at 27" in rear and it looked looooooow. i believe it is 26.5 in front if i put the front crossmember 4" off the ground. before hacking my car apart i screwed up by not measuring the ride height and some other stuff. i built a jig, and spent all day getting the car onto it. what a pain.
-dont ever hack your car apart without a clear plan of what you want to do. lmao

Re: 401 twin turbo new track best
Would there be any interest in my turbonetics 72 mm hurricane turbos? 1300$ for the pair plus ship?
Hurricane silvias t4 72mm with f1-68 turbine and .81 ar
Or 650$ each plus ship

Re: 401 twin turbo new track best
Car is getting 10 pt mod but thats still only 8.5 cert. 25.5 is just way to much bar for me and its use. Maybe someday if i retire from street duty
Turbos are sold so time to look at upgrades.
See 7's this season

Re: 401 twin turbo new track best
Well turns out motor is hurt. When i fragged that turbo early last yr, it ate some stuff. Always had a oily plug on cyl 4. Well did a warm compression test and had 28 psi in there. The others on that bank were 110-120. Cyli 6 was 90-95, as it had a small ring cut groove from first build that i left in there. Brush hone to get it on road again
So cyl 4 looks pretty rough on the piston and head chamber. Dimpled very hard lol. So need to decide what to do here, replace 2 pistons and redeck heads? Get it running again or let it sit and build a new one lol
But ran 8.2's with basically 7 cylinders

I'm sure at full boost there was enough compression to light #4 no problem.

Man that thing just goes even with an upset cylinder! Crazy. Are you planning to bust the 7.99 mark this year?

Re: 401 twin turbo new track best
Probably not gonna get it back together this year. It depends tho. I could try to throw in 2 pistons and deck heads, get it to go, taking a power loss on cyl 4/6 as they will likely compress alittle lower than the others due to bore nicks/groove cut in that wont hone out
Assuming i have enough room to hone.
Not what i want to do but i might have to just because i want to have the car this year lol. I def do not wanna overbore this block and buy new pistons

Re: 401 twin turbo new track best
Those blocks are rated for 500hp. You're pushing twice that at least.
You were going to become a member of the "I drover over my crank" club.
A SHP block would be good for someone like me, who is planning on keeping it under 700hp. For you guys who want to run in the 7s, you need some serious race parts.
Why don't you go LSx ? You start off with a stronger main design to begin with. You already have the electronics to run it.

Re: 401 twin turbo new track best
As far as the SHP rating, yes, it's bull, but you still maxed out the block. And when you told us about your 2016 plans I said you were going to break the block, which is true. As engineers we rate things at 80% of their stress point. You've far exceeded that. Sell the block to someone slower, and build the little M.

Re: 401 twin turbo new track best
Then why do the big time guys run ls next block with sbc mains? Sbc oiling system is alot better too. Y block tunnel is weaker i heard and produces windage
It takes alot to keep an ls alive at big power, which sbc guys dont seem to have issues with little m blocks and equal

Re: 401 twin turbo new track best
The LSx mainline is stronger due to how it's sunk into the block. I didn't realize that was even a debate. I don't have a dog in this fight, I'm an SBC guy. I'm just saying. From an engineering perspective, it has a stronger mainline with less potential for deflection.

Re: 401 twin turbo new track best
You guys just went all over the map.
A Stock LSx block is stronger than a Stock (or shp) SBC block.
The "next" LSx block with the ford bearings and the splayed mains is for 2500+ hp applications.
My point was that guys with STOCK 6.0 blocks are making 1500-2000hp with minimal problems. A stock, or even an SHP SBC block is going to grenade at those levels.

ERL blocks seem to hold up decent but are a highly modded prepped race block based on factory casting
Stock ls block is better than stock sbc
About even with shp
The webbing in the area between mains and cam tunnel is weak on the factory ls iron blocks

Re: 401 twin turbo new track best
Yeah ok, Show me a 6.0L block that will be able to keep the heads down or keep the cylinder walls from splitting open at the kind of boost needed to make 2000hp. 2000 real hp, not 2000 internet HP in your lala land where a stock block 6.0L can reliably make it. stop talking out your a$$.

Re: 401 twin turbo new track best
"The SHP was designed as an upgraded stock replacement block. It is cast from gray iron and incorporates all the most sought-after features of the various evolutions of the Gen 1 small-block such as siamesed cylinder bores, priority main oiling, and four-bolt main caps on the center three saddles. The SHP has a standard deck height of 9.025 inches along with standard 350 main bearings and standard cam bearings. It also has provisions for OE-style roller lifters and spider. "
They don't even mention a specially alloy blend, which the DO mention on the other blocks.
Sounds like a standard cast iron block with splayed main caps. What makes it stronger than an identically prepped stock block?
