i thought stock PS pump does have an oem heat shield. but more is better in heat shielding.I would suggest a proper heat exchanger sized similar or larger to stock 90 turbo engine oil cooler. at what temp does the ps fluid boil? 300+ deg F? seals, gaskets and hoses don't appreciate high...
most aftermarket fans test flow at "0 inches of water" pressure differential. the fans are in a room and flow through the fan gets tested; there is no adverse pressure gradient. manufacturer's specifications should be checked. if the spec is 3000cfm at 10A the fan won't flow that much air in...
Why not run a GM or aftermarket brand ethanol content sensor and have it adjust the global and timing maps on the fly? Some folks put the GM sensor post fuel pressure regulator due to small pipe diamerer. It has been discussed on forum in the past.Good luck.
There should be a check valve in the intake manifold to brake booster hose. Stock one is gray. You should be able to blow through it toward the intake manifold only.FYI - If the fluid can't flow back into the master cylinder reservoir some of the calipers may drag. The simplest test is to...
They used to sell a universal cap. It was a large cap (3" or 4") with a rubber seal on the bottom and a fitting in the middle. They used j-hook bolts and a piece of chain to secure the cap to MC or MC reservoir. You could probably make one fairly easily. A piece of rubber, a piece of thick...
A few years ago I saw a press release by a euro clutch maker, Sachs maybe, for a pressure plate mounted hrb. It was for a competition clutch, pull style. The non rotating part of the hrb needed a positive mechanical stop so hoses wouldn't get damaged. The whole point was that no matter how...
Isn't there an overbore rebuild kit that fits 3s mc that we have been using for years? Chuck the old mc in a lathe and presto: a bolt on oversize mc. What am I missing?
When you "took off the shift cable linkage" was it at the transmission or at the shifter? If at the shifter then you may want to make sure that the transmission cable bracket is bolted to the transmission properly. The "washers" that fit between the transmission and the bracket are bushings...
Is this cage for safety or for looks? Your goals are at odds with the main reason to install a cage. Cages are generally incompatible with passengers, especially back seat passengers. What would happen if you got in an accident? Your rear seat passengers would smack the tubes. Might as well...
Using a hand file to make a flange flat is an exercise in futility. It should also be understood that both flange surfaces should be flat and that the bolt holes and threads should preferably be perpendicular to the flanges. Even if both flanges are flat but the bolt holes/threads are at not...
As has been mentioned before, the air will take the path of least resistance. The air will flow from high pressure to low. If there are large openings next to your radiator the air will mostly bypass it. You ought to build a shroud next to your radiator and close off any openings and make...
I'm sorry to litter the bandwith. I have no experience with aem. To my knowledge some of the aftermarket systems number the cylinders by order of injection/ignition so:(EFI) Logical

A part of the answer is that most hill climbs are very short duration events. Imagine going out to the track and driving two to three laps and that's it. Another part of the answer may be airflow management.
AF ratio numerically higher than 14.7 is lean not rich, if your vehicle is running correctly. Therefore you shouldn't have excess hydrocarbons (fuel) in the exhaust. The o2 sensor just compares the oxigen content inside and outside the exhaust pipe and that is all. If your engine misfires and...
My understanding is that the OP is just bypassing the thermostat thus pushing a bit more water through the stock radiator. The problem as I see it is that although the water runs cooler the water pressure inside the engine has been lowered possibly leading to localized boiling of coolant inside...
Melting point for aluminum is 1220 deg F while we may push up to 1600 deg F on a regular basis. Head exhaust ports are heavily water cooled for a reason. Good luck.
I would prefer the back or top of the rear BS hump for a vent, as long as there is enough room to work on/remove the starter. The crank sprays oil as it spins, but the oil leaves mostly in a tangential direction clockwise when looking at the front of the engine. The top of the rear BS hump...
You may be better off using the large square pad next to the inspection bolt as a vent. I would say to put as large a fitting as possible on there - weld or drill/tap or drill/epoxy. The reduced air velocity with a larger hose ought to minimize oil flow. The baffle may be something as simple...
IIRC the oil pump has a small oil feed that goes from the right side of the first crank bearing, looking at the front of the engine, and feeds the front side of both shafts in the oil pump. Contamination may build/catch in there and cause the oil pump to seize later on.On the other hand...
Please let me elaborate:Looking at the OP picture the cylinders go like this: 4 3 2 1Cyl 4: Route the wire following the arrow next to the spark plug hole to the back of the valve cover and into the far left coil tower.
Cyl 1: Route the wire following the arrow on the valve...
Both Sparco and Momo make quality parts. I have had a Momo adapter installed and it worked as intended. The ribbed part is actually a plastic cover. I also installed a quick disconnect and a 2" extension ring to bring the steering wheel further back.Good luck.
I'm not certain about longevity but I was looking for simplicity and consistancy. The stock system has too many points of failure. With an HRB it either works or it doesn't, while the stock system has many parts that may fail. My original plan was to drill a couple of holes on the in the bell...
Sensor wise I would look at:auberins.com, Temperature control solutions for home and industryTemp and pressure sensors and controllers - I would check all of their sections, not only automotive.http://www.sparkfun.com/Multiple degree of freedom motion sensors - accelerators...
I would suggest that a cooler of some sort is very important. You could check the installs of starion/conquest intercoolers on Visual Frequently Answered Questions - Home Page under the intake section.You could also go to a junk yard and grab a used AT transmission cooler from any...
To measure the pressure in the head an option would be to get a double banjo bolt and install it at the turbo oil feed location on the head. Many motorcycles use double front brake hoses so a double banjo should be easy to find in a bike shop. Just verify that you get the same thread size and...
I haven't used e85 yet but my math seems to support that you would need to enter close to 75% of the injector's actual size.If you have 750cc injectors and want to add 1/3 more fuel due to e85 you would need to get 1000cc injectors in order to run e85 but enter 750cc.750+(750/3) =...
I believe that any PS system, especially one used on a track car needs a cooler. A cheap heat exchanger would be an automatic transmission cooler from a van, suv or truck from your local you-pull-it automotive recycling center :) . Good luck.
Get a piece of unistrut ( "C" channel support with holes in it) or a flat piece of steel at your local home improvement store electrical section and a piece of conduit/black iron pipe that would fit over your breaker bar.Bolt the steel to the crank using two flywheel bolts. Rest the steel...
Another option would be to use a header tank from some of the newer vehicles - VAG products - audi, vw, or Ford Windstar, etc. For example Ford Windstar header tank has a 16psi cap. Some vehicles also have a liquid level sensor just like a stock dsm and that could help detect the coolant loss...
Just a side note, not necessarily pertinient here, but I have previously read that the F3 cars, as well as the new NGTC turbo touring cars run about 75C (just below 170F). The ECUs start retarding timing as water temps increase past 170F. Of course, these vehicles are true race cars that live...
Has the master cylinder been upgraded as well? If the calipers have been upgraded the master should have been upgraded as well. Bleeding may help some, but the if the master is too small the pedal will have long travel and give a mushy feeling even if bled properly.Good luck.
When the throttle body (TB) gets closed the pressure spikes in front of the TB and the vacuum is created on the back side of the TB. The whole point of BOV is not to have high pressure between the compressor wheel and the throttle body as the only place it can go is backwards through the...
You would have to loop the line(s). Once the thermostat opens all the oil should go through the cooler. If you put bolts in the oil cooler ports on the filter bracket your engine will lose oil pressure and seize.

You do realize that if caught with the test pipe you may be fined up to $10K and jail time, right? IMHO a couple HP just isn't worth the risk. You would be better off getting a larger diameter exhaust and cat as suggested above.
After the engine has warmed up you ought to have hot air coming out with the heater lever turned to hot. To me that indicates that the coolant level is too low and heater core has never been filled. After you replaced the head gasket did you run the heater at full blast when you re-filled the...
The biggest problem seems to be the driving technique. A good driver has to be sympathetic to equipment and understand how it works and what it can and cannot do. You should at least give the synchros a chance to do their job. Even guys running dog boxes that can take WOT shifts and need a...
Is anyone using a hydraulic release bearing?I was on Tilton's web site a while ago and read HRB install manuals and two of them caught my eye - primarily Honda HRB and MR2 HRB install manuals (98-1115 and 98-1116 respectively). The instructions for Honda mention that the HRB should be...
The harmonic balancer may have separated. Have you physically verified that the engine is at TDC and that the mark on the pulley lines up with "T" on the timing belt cover? I think you ought to remove the spark plugs, grab a really long screwdriver or a socket extension and see if the engine...
