All Things Chev

Mark, funny you say that at BD are telling me the same, but the guy with the SC in WA I am talking with had his dyno tuned to get it running sweet after he changed the nose pulley, so maybe that simply entails adjusting the fuel rate into the pump. BD tell me the swap over process for mine is plug and play. I am still wondering about the whole 'timing of the pump' issue that seems to be an important part of the TD42 journey when a pump is changed.

Chev pumps are a peice of cake. They are pin timed. You do have a small amount of adjustment for timing but not a lot. Line the marks up. Pull the pump off. Line the pin up and put the new one on.

Thanks Matt, have asked the question of BD but as usual not get an answer.

PB, I'm assuming you got the intercooler intake manifold?
Which will mean a pump and radiator are required as well.

No I am not going with an intercooler at this time. If I do, I will go with a water to air unit modified using the A/C gas as one of the guys did up in Nth Qld. I didn't like the pancake assy between the blower and the inlet manifold. I am going to stick with the currnt radiator I have for now, but have ordered a Duramax fan and new radiator cowling, plus will still have my 2500cfm booster electric fan on the front of the radiator for low speed driving - only gets warm at high rpm/slow speed stuff. BD do have a custom aluminium unit they get made but its 1900 and I may not need it. What are you proposing for yours?

I have this setup:

Nice, where did you buy that from? What size/make blower? [ can't quite read the name on the blower)How many ribs on that serpy belt - 6 or 8?

Hi PB, it's the Bullet kit, TE2300 is the supercharger, I think it's 6 rib, but haven't checked.
I'm trying to run this belt setup for my engine, without vac pump.

OK, I have upgraded my pulleys to 8 rib because the 6 ribs stretch very quickly. BD is currently making 3 sets of 8 ribs, one for me, the guy I am speaking with in WA who has the Optimiser wirt 65mm pulley and a guy in cairns. Bullet are upgrading the nose pulley to 8 rib and have acknowledged the shortened life of the 6. With your beast I am tipping the 6 will last a very short time. So which vac pump are you going with? My upgrade from BD has the vac pump but unsure if its on the back of the alternator or otherwise - must check that. Also, am upgrading the alternator to a 140amp unit. Once I have it in hand will see if I can get a higher capacity in the same frame size - greg isn';t much help in this regard. That is the same kit as i am getting, I think.

Who's 8 rib pulley did you go for at the crank?
