For those of you that may be having a rough time getting your transmissions to stay together for racing requirements...... I recommend the following Web site: 84Dave

And Rules permitting, use an oil-accumulator on your wet-sump oil system. Canton or Moroso? In that manner, as you speed through a race-track corner and the oil slams to the side of your pan sump,...
-
To all of you 4-cylinder engine folks............ for what it's worth. If you are using a 'dial-back' timing light on your engines, it could be junk! We checked ours way back when, and it was...
-
I suspect that whoever 'built' your 2.5 'failed the test' on rod bolt installation. Every 2.0/2.3/2.5 I've ever built? I use ONLY ARP rod bolts with their lube. And before final assembly, I go...
-
Did you spin a main or rod bearing? Did you at least Plasti-Gage the clearances when you assembled the engine? Do you have an oil-temp gauge down in the pan? Did your oil-pressure gauge look OK at...

In the simplest of terms, HeadHunter explained it pretty well. -Dave-

Save some $$$ until you can purchase a braided hose kit! That's what should be used. -Dave-
-
As suggested, talk to the cam manufacture. And also tell the manufacturer the rpm range you intend to run the engine. It makes a difference when it comes to spring pressures. -Dave-

A Happy Holiday period & Happy New Year 2016! We're here to help each other in readiness for the 2016 race season. Inspect your race cars thoroughly. Especially your safety equipment!

In the past few weeks, I've seen little or no activity on the Subject web site. Is the site still active?
If so, why the slowdown? 84Dave

Do you really need an alternator? Yes indeed! The difference between a pure battery @ 12.5VDC & the alternator outputting 14.3V will provide about 2000 volts additional across the secondary
output...
-
I suggest you consider purchasing the relative new Air-Fuel-Ratio (AFR) INNOVATE digital gauge with its digital O2 sensor. Then consider putting you Rat Rod on a chassis dyno and pull the engine...
-
Doug..... Regarding rod-length to stroke ratio. A lot depends on the operating rpm band @ the tracks you run. It's a fact that for any given stroke, a longer rod slightly narrows the rpm band between...
-
I'm not the world's expert, but................ On pavement, we keep the weight down low. That slightly decreases the height of the C.G. So the race car won't roll to the right quite as much. We also...
-
Install a fuel-pressure gauge up at the input to the carb. With a line back to the gauge inside the (not a nice word)(not a nice word)(not a nice word)(not a nice word)pit. With power applied to the...

Contact Esslinger, Schneider, Crower, & Comp Cams. Fill them in with your specifics above & they'll be able to tell you the best cam to run. Dave

Realizing that for every .1 in final gear ratio change, the engine rpm will increase/decrease about 125-150 rpm. Dave

Recommend you contact Esslinger directly. They'll recommend your needs. 84Dave

Profile.......... I'm far from being a 'puter expert, & searching/moving things around on these forums. But if you, or someone you know, can search out my past screed on exhaust systems and post it...

Haven't seen much race-talk traffic here lately. 84Dave

We've used NGK plugs for many a year with great success. However....... make sure the plug is a J-gap version. And if you can't get a J-gap for your specific engine, modify the plug to a J-gap...
-
The 350/500 Holley 2-bbls were designed for V-8 engines. The PVCR (Power Valve Channel Restriction) is much too large in diameter for the 4-cylinders. I recommend contacting Bob Oliver @ Competition...
-
Some minor help with some quick math on your part. Tranny gear X rear gear = final ratio to the tires. For every .1 change, up or down, in the final ratio, the engine rpm will change 125-150 rpm....
-
I would suggest your problem may be the camshaft & its max lift/duration/LCA. Have you flowed the head on a bench & determined the max valve lift where the intake flow no longer increases? My...
-
You're thinking is on the right track. Actually, a 3-speed, with reverse, might be best. Depending on how many different track lengths you race. Needed....... reverse, low for the pit area,...
