Went to Autozone and picked up a Melling JB-969 lifter for $3.69 . On the box is said "made in the USA" . Has ball check-valve and flat disc oil metering with wire retaining clip. The picture shows the two-part lifter body with the hardened foot, this is particular to Delphi lifters only. So it...

Just now noticed (this may be old news to everyone else) that Federal-Mogul / Sealed-Power is listing a hi-rev hydraulic (flat) lifter with part number HT-969R. Haven't seen any specifics but the "R" designation on the chevy lifter, for example, meant c-clip retainers instead of retaining wires...

Does anyone know anything about the DA-31 345 LPH fuel pump? Chart shows roughly 68 gph at 70 psi. Looks like a Bosch 044 to me, other than that...

VIN is: 6G2VX12G14L260789 Thanks

Kettering University in Flint, Michigan is one of several that have been tapped by the Department of Energy (DOE) to study the impact of higher ethanol blends on older vehicles. The use of up to 15 percent ethanol in gasoline for 2007 model year vehicles or newer has been approved by the...

While I was scanning through the corvette forum board, I came across this post: NEW, The Best in tank fuel pump, denso kyosan 390lph @ 40psi - Corvette Forum Kyosan p/n 895091-0810 This gives us another option for an in-tank pump. While not the most powerful in-tank pump, it is a step...

Here are some specs for late model stock-replacement roller-cam springs: Federal-Mogul/Sealed-Power VS-1628 Beehive Free length: 1.945" Wire diameter: .187" Spring rate: 350 lbs/in Closed: 78# @ 1.71" Open: 228# @ 1.278 Coil bind: 1.18" Melling VS-2222 Free length: 1.98" O.D...

A letter I got asking for support of E15: -------------------------- Dear Ethanol Supporter, There is one week left for you and other clean fuel proponents to actively support one of the most important issues in the ethanol industry today: increasing the allowed ethanol blend to E15. This is...

Here is a chart of fuel flow curves for bigger injectors (70+ #/hr) and pumps (weldon, aeromotive, fuelab, sx, etc). Injectors are at 25 psi boost only, didn't think it made sense to do it for any less. Pumps are at 13.5 or 14 volts. If you're looking to size pumps/injectors, look for a...

Anybody seen this walbro E85 pump for injection? http://www.autoperformanceengineering.com/doc/walbro_e85_pump.pdf It's not enough for a main fuel pump but may be ok for alk injection. And it's E85 rated. http://www.autoperformanceengineering.com/doc/walbro_e85_drawing.jpg

In order for this not to be a duplicate post, I have included E85-specifc information on the attached chart (note the hp estimates based on E85 bsfc). This is a continuation of a discussion that evolved into what injectors were suitable for which fuel pump and/or which pump could support what...

Well I wanted to post this in the thread that originally generated this discussion but i was told the E85 section wasn't the most appropiate so I'll post it here. Anyway, the discussion evolved into what injectors were suitable for which fuel pump and/or which pump could support what injectors...

Does anyone know if Turbolink v 4.0 will display the data at a faster rate or does it just log more data? This is with the SM fast update patch code in the chip.

About to start tuning on a dynocom dyno. Chip is a TT 5.6 for stock injectors. Have a PLX wide-band in the test pipe. Have turbolink on a laptop. The dyno operator wants to remove the stock location O2 sensor to install his wideband. Will this screw up the calibration? Or is it ok to run without...

Does anyone still make the adjustable stealth (stock-looking) fuel pressure regulator?

Has anyone else run into this? I bought a new stock replacement radiator from AC-Delco p/n 20269. I found that the fittings for the new transmission cooler are wrong. Original OEM fittings are 1/4" NPT. This is where the 90 degree adapters screw in that adapt the 5/16" flare trans lines to 1/4"...

What's the biggest turbo I can run on 30# stock replacement injectors, adj fpr , 340 fuel pump, 3" dp, stock D5 and an otherwise stock configuration?

From what I can gather, it looks like the BSFC of E85 is .60 - .65 (compared to .50 for gasoline). That would say that the calculations for the maximum hp supported by the injectors, derived from max flow rate, would decrease the hp number by ~20 - 30% compared to gasoline: Hp = 6 x...

In trying to get an aftermarket 3" DP installed on an '87 T, I noticed that the rear of the DP was hitting the frame. There is no "slop" in the mounting bolts to allow the rear of the DP to go upwards. ( I left the bolts very loose). So I started looking at the possibility of the motor mounts...

Instead of running a stand-alone alky system, why not use E85 ethanol in the gas tank? It's 105 octane, so you should be able to dial the boost way up. I know there are some fuel system material compatibility issues and the chip will need to modded for the different stoich value, but is this...
