Bill,
Im not 100% on the vac pumps.We put one on lil brothers dragster because everyone kept telling us how much we would pickup. Nothing not a .01 differance.His car is perfect bracket car it will not go faster I dp not care what you do to it.
When I questioned a few folks about it .I was told well if you had tight ring package with very little to no blow by it had less effect. I can only assume those who found et gain had very low drag rings where as we had total seal gapless.We did have more drag,but then we apparently did not need vaccum pump to pull the crankcase pressure out of engine.
I figure your buddy has low drag rings also. If so vaccum pump will probably add few horses.With comp cars everything helps and they do not pass up anything that might make a hp. Would love to run,also love to be rich enough to run that class.
BAck to gas ports. WHile I do not own dyno. I do have 5 sets of pistons for this deal. I plan to gas port one and chenge them and see if any differance.No not back to back test. I should be able to get pretty close on conditions and see what change it makes. I appreciate the points made and they are good arguements. Still would like to try. Worst case I have 4 sets of pistons for the two motors I have sitting here. If nothing else I am experimental Son of Gun(gottcha Glen you thought something else coming).This is why we had computer on TA/FC when most thought useless,had lean richening valves in 1990 when a lot thought just stupid for alcohol car. What are they all running now. Also reason I have shelf full of odd cams for hemi's. Have some with huge exhaust because it seemed a blower motor would need more exhausted to get more incoming air into cylinder. IMO experimenting is big part of drag racing and part I love.

I totaly understand how the accumalator works and why. I also understand that with the NA mtor I am running using Blown engine parts thru out I have access in few areas. 110 to 120 lbs OP at idle and having 10 quarts in ,thers no way I am going to pull near the oil as quick,lower rpm lower rpm accelerating rate and not to mention 4500 versus 7000 stage rpm. I don't see the pickup becoming uncovered except maybe on had deceleration like dropping at the finish line hard. In this case it would be good insurance. Having less oil in the pan which would be furthure down from windage tray and just below tray has to help with less chance of oil to pulled up into hurricane going on above.
I don't expect to pickup 50 horses or nothing like that. I have talked with a lot of guys who have picked up .10 from running less oil.Yea I had hard time believing first cpl,but after more tell you same thing. Yes Im sure some of them had too much oil and it was too high of level for the pan they had. I love going faster but not at cost of needless risk to engine.
As for weight you might be right about trade off. IMO if it equals out and helps prolong parts life I am fine with that. This is bracket deal and consistent is f utomost importance. If hitting a race where minimum weight is big deal I will just remove this along with full Chute body and go to the short body.
Baffle may or may not matter.I do not see how it can hurt. Plus super easy to remove or add.
R-M seems to have different view about gas ports. Agree if was blower motor no need.This is injected only and not even nitro, just , plain old alcohol.
Reading R-M site and seems they built a motor w/o Gas ports at customers request.It was down 50 hp. Pulled it did gas ports NOTHING else. Put it back on dyno and it was up the 50 and where they expected it to be. Not knocking anyone but hard to argue with Reher-Morrison on what they found and are willing to backup
I am setting this deal up to be as versitle as possible and be easily adapted to as many class' as I can. Not to worried about making a Jr. Fuel settup the engine cost is out of my range now days for that one.

Going to have one in new pan I am working on. Figure easy to make allowance for it now.When its warm out I will just pull it and cap off.

Matt Shaff's Engine Shop / oil returns,valley tray and other small hp increases
« on: February 16, 2014, 10:06:00 AM »
After reading few things on oil control , I did some real close checking on my TFX hemi stuff. Returns from heads suck. Small 5/16 holes and rear left does not even return. I am adding some returns from block just below deck where heads drain to and going into pan below the windage tray. Going to run aluminum line since no pressure and has to aid in cooling some.
Also added a piece of aluminum in lifter valley to help keep oil off bottom of intake and Hopefully keep it cooler. Also had oil drianing to ends so as to keep oil draining back on top of rotating assembly reduced.
As posted on another thread I.m also looking into adding a oil accumalator to system.
HAve already added gas ports to the pistons in hopes of picking up few extra ponies.
Figure its worth cpl horse's maybe not enough to notice by them selves but they add up.
Wondering what other tricks some here have done or tried and what results where. Also any thoughts on above ideas are always welcomed.Might read and ignore, but like to give any idea a look.

Matt Shaff's Engine Shop / oil accumalator
« on: February 16, 2014, 08:47:23 AM »
Have been researching oil accumalators. Never ran one but then always ran blower motors ans just primed system with plugs out and spinning motor.
Seems there is side benifit of being able to run little less oil in pan and reducing effects of windage. Sort of poor mans simi dry sump. Good amount are claiming some et advantage to them mainly because of windage reduction. Since I have 10 quart pan and can easily get by with less I'm thinking I could run 7 in pan and 3 quart in accumalator. With pan I have dual trap doors and windage tray plus heads return straight to the pan below windage tray.
Anyone with reason this might be issue let me hear your thoughts.If you run or have run a accumalator let me know your thoghts or findings.

Spud Miller's Cave / Barrel valve ? for Spud
« on: February 15, 2014, 06:59:10 AM »
Spud,
I was playing around on your web site with calculators. Good news is they where almost dead on my SWAG so they must be accurate
. Question I have is . While checking numbers on N/A system and changed the BV from cube to K style the pressure made big jump.82 to 123 lb.s. Wondering why? Assuming this pressure calc. is for in front of barrel valve. It was a 8 line system .039 nozzles ,6.78 gpm pump 2.753 to the motor and .136 jet. Checked it with cpl ohter systems pretty much same results. Just got me wondering.

Never tested it.I have read hundred articles on it. Seems it all depends on combo. If your cam is little small then it seems to help.If your on the edge of too big seems it push'e you over and actually hurts but giving more duration. Some combo like mix with 1.5 on o intake and 1.6 on exhaust .

I see the two as lot safer. Odds are if brake they will split and go outward.This would leave me in the middle instead of the bar in the middle of me. JMO aqnd probably worth less then 2 cent.
I am mounting mine with top 2 bars to frame rails right at kidney bars.Hopefully never to break but id something stupid happens and back end hits something and breaks them I figure they will be deflected away from me. I am running lower bar to center bar ,almost to rear end(high chair car) putting it on sam plane as lower frame rails/Using 1 1/8 mainly with sleeving and adjuster on bottom bar. Hoping that after get it tuned and weight where it needs to be I can basically run w/o bars.

« on: February 02, 2014, 10:36:26 AM »
yea normally here in NC 30 or 40 degrees.This year lots of single digit and my shop not setup for heating much. I like cold weather but working with steel when its been that cold for cpl days is just not a lot of fun.
Blower style heater I use is sucking some $4.50 a gallon kerosene. ABout 20 bucks every other day or so.Bad part just got 2 custom cabinet jobs and for glue to setup I'm going to have to keep 55* plus 12 to 18 hrs per day.
