Hi Leon, Because the options available for de-mountable members under NZ regs didn't suit my application, I used the specific engineering design route where I had to get an engineers report. I used Dwayne Zander, a design engineer who works at Gary Douglas Engineers in Palmerston North...

Looking awesome Leon! Superb. Cheers, Andrew

Hi, can't talk directly to the LS3/480, but I had the same issue on a multi-point injected 383 SBC with aftermarket engine management on it in a project car for the street which had manual transmission, and where manners were really important. I had a hydraulic roller cam of similar specs to...

John, the car looks superb. Great stuff! Cheers, Andrew

Hi, in my inverted race application, I have a Moroso catch can (with top mounted breather) receiving oil puked from the top of the trans that is directed into the top side of the can. This drains directly back to the trans from the bottom of the can through a modified fitting in place of the...

Hi, your ECU may have the ability to drive a 0-5v gauge directly off an auxilliary PWM or similar output. If so, that would negate the requirement to install and maintain another WB sensor in the exhaust. Cheers, Andrew

Hi Dave, good to hear you are getting near the fun end of the ITB conversion! In terms of flow from the lift pumps, assuming they are charging up a surge tank or swirl pot arrangement, you obviously want comfortably more volume from the low pressure system than the engine will ever need...

John the car looks bloody superb. My M1 with cast iron chev was 920kg without the body on so you have done a fabulous job building it to a low weight - I'm sure it will be a weapon! Cheers, Andrew

Hi Wolf, do you have any plans to make those exhaust headers to order - just as they are shown with no merge collector? Cheers, Andrew

Looks awesome! Keen to see it come together. Cheers, Andrew

Hi John, I have no empirical data on whether they work or not because I haven't run without them, but I do know my front brakes get pretty hot when racing. I've made a few running changes to keep front brake temperature under control. I've got Wilwood 6 pots on 355 x 32 rotors front and...

Hi Russell, I'm controlling a Hilborn 2 7/16 8 stack EFI set-up on the 440 Chev in the McLaren M1 replica using a Link G4. The main tuning challenge for me was related to how much throttle area you are managing and how touchy that is down low (i.e. idle control and stability during warm-up...

Hi Tim, another thing is that some Holleys do not have a secondary power valve, meaning the secondary main jet area is relatively large, which increases the chance of raw fuel dribbling from boosters under hard braking. I found vent baffling, attention to float level, and installation of a...

Hi Cliff, this is the Speedmaster (formerly Procomp) stack set-up with a FAST ECU. https://speedmaster79.com/pce1481032-ford-sb-260-289-302-windsor-down-draft-efi-stack-intake-manifold-system/ I would say that the three important considerations are the quality and the dimensional...

Colin, I think you are onto it. Different car but my EB2 falcon would not rev past a hard ignition cut at fairly low rpm with the plug to the VSS removed from the gearbox. If you don't have a VSS signal could you send the ECU a tach drive output or something like that. All it probably needs...

Great stuff Russell - looks awesome! Would love to see it running. Cheers, Andrew

Hi Chris, you should be OK if you position the O2 sensor as near to the engine end of the main collector as you can. If you have a foot or more of main pipe length after the sensor the impact of reversion pulses should be minimal. Cheers, Andrew

The main thing to remember is that the timing curve in a carb engine is usually a bit compromised by the practical limitations of traditional distributor centrifugal and vacuum advance systems. On the few EFI engines I've tuned I start by finding what the engine actually likes best at no...

Hi Udo, Looks awesome! That thing is going to be berserk to drive - in a good way! Cheers, Andrew

Yep go with McLaren Russell. I have been entering my car as a McLaren replica in everything I've done so far, and they just print McLaren in the programme and no-one cares. Cheers, Andrew
