well, holey $hit!  rofl damn that was a lot of work arounds  rofl  glad you got it sorted out ....for now? just kidding i hope this is the last time!!!!! so any thoughts on the head gasket issues? i new good year sold there belt line to cont, i know a guy that still works there as my little brother used to. they have so many lines it would take the right guy at the right moment to ask the right question to as to spark the right memory just for a chance to find something  LMAO

Talking with Comp has me believing the cam was actually the issue with the Brodix CV heads. The heads flow so much at mid rpm (as do the SB2.2,hence the new cam)that the VE is actually way above 100% and at mid rpms will actually over pressure the cylinder(sort of like too much boost way too early) . Using the E85 prevented any detonation but also allow it to run really well while slowly pushing the gasket. That's why it ran so long before it pushed to water . They suggested O ringing the block or MLS gaskets but I'm done with them at least for now. Honestly,I'm going to hold on to them until I decide if I will give them another chance with a different cam that will still fill the cylinder but also bleed off excess compression at the mid rpm range.

that actually does make sense.  how much cyl pressure do you have or had on cold crank? if nothing else you def were consistent on life expectancy with your head gaskets which was no coincidence !

Can't answer that . I didn't check because Comp said cranking compression wouldn't indicate a problem and neither would compression ratio. I do know I was @ 14:1 and that is lower than  many are running today. Comp said it was a cam issue or rather a poor cam choice issue. They said the one time was likely aggravated by the uneven torquing due to the torque wrenches not being calibrated the same but was not likely the root cause.

Well,FINALLY,the SB2.2 is going in the car.

oh i know that  :m    sounds like this new cam should dial the cyl pressure down a bit in mid range.    besides once you get this one finished the blue " mini   ;D " rail  will be freshened up quickly  :nw  :D

how muc does that blue " mini " busa rail weigh again?? i know its a little heavier than mine.  i bet mine weighed 1650 to 1750 with the turbo busa in it.

IIRC with dune tires,full tank of gas and no passengers it was 1850ish.Dirt tires added about 150 I think to that.

out of curiosity.....did you even data log even a short run on the sand in your v-8 rail?

the reason i ask is ( based on what the cam guy told you) i would think that would be shown on the data log. i do not doubt it at all, i would really like to see it on the data log as imo that would be very impressive!  if that is true ( again i do not doubt it as it makes sense) that would mean you actually built a nascar engine for your rail !!  rofl talk about taking it over the top  :m ;D ;D i don't care who or what anyone thinks, to build that and stuff it in a rail ......i have to tip my hat for that one!  ;D that just makes fast look normal  LMAO LMAO

on the data log i would think that in the midrange at prob 62% and greater tps, one would see something in the range of 95 to 101 kpa?? your ve should be up as well ? if do have the data log save it because i would like to see it just because. i don't know and i bet with the limited run time but say if your inj's were well matched for the build then you were prob say 65% in that mid range? actually interesting to think about when talking about an n/a motor when you think about it!

VE @ 44% TPS was reading 107% with load of 70% IDC was 38% @5000rpm

VE@100% TPS was reading 111%  with load of 95%  IDC was 80ish @7500 rpm

I did not have KPA readings but load and KPA pretty well mirror each other.

IDC was high at 7500 due to dropping fuel pressure. Got to sort that out. I think the engine just gulps fuel faster than the pumps can supply under fast engine acceleration . Base pressure on the gauge is set to 43psi but logs only show around 38. Sensor and gauge are right next to each other. FP drops consistently on any fast acceleration condition.

 The FAST throttle body has 8 injectors that are staged to run at low load on 4 with the secondary 4 kicking in as needed yet is able to maintain AFR's as FP drops from a logged 38ish to 20ish.This is a return system with the sensor and gauge on the return side after the TB.

The injectors are all 74 lb /hr.

so that it impressive and on fuel pressure do you have a vac line connected to the fuel reg? if so disconnect that, it's only used for forced induction. no matter what dripping down to 20 ish psi is an issue but again that could be vac doing that. just for example....my rising rate fuel reg is rated for up to 100 psi. wasn't easy finding one that actually put a rating on it! mine raises fuel psi 1 lb per 1 psi boost up to 25 psi then it drops to .75 lbs per 1 psi. i run 130 lb inj's also. i tried an actual walbro 450 pump but it began failing quickly or it couldn't move the fuel it was rated for. either way i went to the a1000 which is over kill for myself. the walbro worked correctly for the first several runs but by the 3rd day at st a it started dropping to the point it wasn't supporting 18 psi boost.  i did read a post that load/kpa mirror each other up to 100 at sea level and at altitude that changes but seems to part ways by 80 at altitude. so no matter what your motor moves some air n/a!
