you guys are making good power,we have too.

we only ran 3 passes to the 1/4 and went 198 on 7 cyls.

our best 1/8 in a 4.70 at 164. so i would say we are probably making as much power as you.

we have seen capwalk at 1900 hp + on the lsx blocks. the mains try to twist at that power level.

 

Thank you.

 

Not trying to be negative here just saying that we havent seen an issue with cap walk. We have had more issuses with crank flex than anything. We have that handled now. We have been 200 plus 5-10 times. 160+ in the eight probly 15-20 times. Remember we weigh in at 3450 not 3250. We are currently building a tall deck engine that will indeed have a 1/2 thick girdle. This year we plan to push our turbos to 50+ psi

 

And i weight in at 2500-2600 lbs. Will be fun to see how fast it will go with 2000 hp

 

2000 is gravy i have street cars in that area. We are in the area of 2650ish

 

Wow, crazy to see the big dogs one-uping each other on the forum....

 

If you have issues with the crank flexing like everyone else, how are the main caps not moving/walking. Is the crank flexing between the main caps? I saw you guys went 209 out in vegas, did the car ever make another pass that was 207+?

The reason I ask is your 7.24 and my 7.29 are virtually identical, we were both 4.83 to the 1/8 mile....
3.28 to 3.30
4.83 @ 160 to 4.83 @ 161
7.29 @ 191 to 7.24 @ 209

All of the 7.2x passes I have seen are that are 4.81 to 4.84 to the 1/8 mile are 194-199mph. I am not trying to start **** but knowing the rate of acceleration on this type of setup on the back half and calculating the FPS these cars travel, just curious if there is a possibility of a timing error.

 

you got to remember we dropped 2 cylinders up top, probably would have run 205 or so at about that same 7.24. I really don't think it's that far off Phil. Now as far as the estimated 2600+ hp-i belive that is a little high.

 

I have noticed too.

 

I'm not only using our runs but what I have seen from other top radial teams. The math just doesn't jive in my brain or calculator.

7.18 @ 201
7.21 @ 201
7.27 @ 200
7.32 @ 192
7.29 @ 191
7.33 @ 193

 

Not to technical here but the girdle is cheaper than the arp bolts in my motor, just extra insurance

 

Damn I didnt know yall were gonna get defensive. I have all the data I need to make these claims. Since we put the fully counter weighted billet crank in it we have no flex issues at all. I really dont want to argue.

 

No one is getting defensive, just a simple question. How many passes have you guys made over 207mph?

 

One at 206 and change and the 209. have had several 202-203 passes. After the 209 pass Mark saw the data and was amazed. Only two over 200 in competition though. We shall see this year. Are you gonna go to any races this year.

 

Assuming the rules are somewhat even and the payout is worth the drive, yes.

 

Given the horsepower level I am aiming for I will honestly admit I don't think I needed a Girdle especially one that is extreme and bolts up to the outer oil pan rail. With girdles like this it poses other fitment issues that have slowed up my build but thanks to the guys at ERL for taking a little extra time to help me out I will be able to make my combo work easily with my 7 quart wet sump oil pan. Here is a pic of the girdle; I need to find some others I have that are better but you kind of get the idea. This thing is stout for sure even though it doesn't pin into the bottom of the billet main caps that are pinned to the block.

Imho if you are looking at a build that will take you over 1500 horse a Girdle is a good investment even on an LSX block for sure. Like I said I fell short of that mark for my goals but due to my desire for longevity and my need to over build everything I went with it.

 

come on man,nothing wrong with a little friendly debate

 

How did you modify the windage tray?

 

That is a very good question and as soon as I know I will be happy to let you know. LOL Seriously though I have been told to not worry about it and not run one which kind of goes against all I know about bottom ends and windage. But the more immediate problem is getting a pickup tube to correctly fit this style of girdle. I had a new stock f-body pickup tube and a Moroso pickup tube and neither of them suckers was going to fit up front where the tube bends into the oil pump. Come to find out there isn't too many nut jobs like me running this style of girdle on a wet sump and thus if I would have gone dry sump things might have been easier as KUP performance has a custom ARE pump adapter peace that works perfect with this girdle and ARE oil pan. The problem with dry sump is the price tag associated with it and given my car is a 99% street warrior I just didn't see the need in spending 2600 or more for an ARE dry sump system. I would have loved to have had a dry sump but I still want my A/C for my car and needed the money elsewhere like in my t56 that I figure I will end up blowing up. LOL

I did learn that the C6 style of pickup tube is what the girdle was designed around and would have gotten me started a lot better than the other pickup tubes I had planned on using. But since I also am using an abnormal pan for this build ERL offered to help me out.

So big thanks to Sean and Jeff at ERL for offering to help me make it work by custom fabing me a pickup tube that will work great with the girdle and the Moroso Oil pan I will be using which is not the regular f-body replacement oil pan. They also sent me some longer main studs to try and help accommodate a windage try should I still want to try it and those are what are pictured after I installed them. I do know I will have to do some modifying to make the oil pan I got fit but with the BMR k-member I have I am not too worried about it as the 7 plus quart capacity I will gain for the high volume oil pump I am running is worth it imho.

 

Unless someone is scared.
