Awesome work mate.

 

 

It’s always good when mods pay off. Esp when u put some serious effort into them.

It really is a serious amount of effort in making a set

 

 

Don’t think I would recommend this amount of work for a N/A 500-600hp Holden engine unless your really really keen but for boost there is a large noticeable increase in efficiency

 

 

I’m not a expert in it but I think a lot of the torque come from 1 7/8 for 10 inches then the step to 2 inch, and obviously the increase e85 would of added but it appears there is a good scavenge affect there

I reckon they would make a huge difference on NA too, its as important in NA, as you cant get the fresh charge in until the old one is exhausted.  So the quicker and easier for the exhaust gas to leave the more power NA will make.  The drop in pressure you have seen proves how well they are working, seriously great result, and for a set you literally made yourself is pretty bloody nice work.  If you get bored happy for you to come over to SA and help me make a set for mine

Yeah you would be right actually, big HP N/A engines that flow enough would have big gains in these as well

 

 

Robert valastro comes and stays at my place when ever he goes racing, I spent a good half hour looking at his pipes from every angle while it was on the trailer to get a good idea on how to make myn,

 

he he even come here when I was half way through them so I was able to compare a bit more

 

his pipes are a real work of art and they do work great on his engine, he is making 520 rwhp N/A and 150hp nos on top of that though and at 8500rpm so it needs them and he gained .3 second or so with them

Roberts just swapping to a white VL from his blue VR isnt he? Tuff bloody car (s)  All the numbers you have achieved point to them working exactly as planned, great work.

It is a shame I never got a comparison against them

Yeah robs engine and whole set up is mental, he is extremely good at making a car fast, even on basic set ups he has pulled awesome HP numbers and has a some good little tricks he does
