Do a search it's been discussed. In a nutshell it's a huge pulley and you need max cooling, tb and longtubes and injectors. anything less it creates more heat than it's worth. You will need a trunk tank and killer chiller or meth. Anything larger than a 77 your trading more heat than hp created.
Keep in mind there are cars with 83mm pulley shorty headers 82mm tb and dyno tune pulling more than 520 at the wheels. They have big heat exchangers and big trunk tanks. Cooling is more of a key than pulley size. This is more power than most with long tubes 77mm pulley 82 tb and tune with h/e and engine bay tank.

Not Sure what you mean by that. You can ask the vets. Hulk Shardul hammer down black Benz ect the 70 mm pulley isn't outperforming a 77 without MASSIVE cooling if you think it will my 83 mm will walk you. Learn the platform

You clearly can't read properly !!! Read what I wrote again ,maybe you'll figure it out after .Ill say it in lemans terms for you ,a 77 pulley will walk a 70 setup on the street any day of the week.It will pull timing back after 100 mph very bad!Only way to over come this best ,will be proper cooling and e85 the it will feel like a monster ! to much cooling will have diminishing affects

We will be back with dyno numbers shortly as our car is currently down for our whipple kit fitment and testing.
on a 55 to 135 pull, IAT was 86F going in peaked at 131 and recovered instantly to 90 with the 70mm pulley with the following cooling mods VRP superflo, VRP primary (single pass version) and secondary HE, 5 Gallon Trunk tank (no ice).
This is without methanol or Ice on the stock Intercooler. we have 6 intercooler cores and they will be available as single pass units VERY shortly.
most of you are seeing the same temps on your 77mm. so pull up to a 70mm car with a 77 and see what happens. lol
We had a customer pickup 34whp from a 77 to a 72 clutched with a dyno tune.

3/4 both sides, ours will be tested at the track as soon as it gets warm here. (snow on the ground in VA) But there have been some awesome results posted across the forum for similar units.
