Considering that a lot of us have ponied up serious money to push the limits of the VQ platform. You would think that more people would be excited, over skeptical, with pushing major power. I personally would like to know exactly what this platform is able to handle. But I guess Haters will hate.

I personally can't wait to see what Johnny and Ron do with this monster. In fact can't wait until tomorrow when I get to check it out.

being a de is going to push the presure up a lot, they don't flow all that great, the hr stock cams and timing will run a few pounds less on the same blower, and the vhr with it's tremendous overlap will run even lower, horsepower doesn't follow this as well an hr 18psi can easily make more power than a de at 21. a vhr at 12 makes more power than a de at 18. That is all uncammed of course.

Oh it's great and all but I really want someone to try and fit the v7 (apparently they will put the v4 housing on the v2 case now) with it's bigger 60k+ rpm limit and 2"larger impeller. <- if that fits it will be cool. the V7 should bolt to the v3 bracket the volute is just a little bigger or if they somehow fit a T-trim impeller on the v3

I love your profile pic but I prefer no carpet on the beaver

Haha yeah but its funny

Ron was the 1st person in motorsports to give me a chance with cooling his drift cars.. The man is a genius with engines.. He has taught me so much, and is one person that gets my deepest discount on product no matter what..

He is the man, and I'm looking forward to hearing more about this build.

Agree with you to some extent. The vhr is a superior engine, has higher CR, bigger displacement and better VE therefore it's natural for the same compressor to create less boost in the manifold, but the net result shouldn't be dramatically different if they have a similar kit and reasonable tune. When you cram air into the engine a lot of variables in a NA engine that were important becomes less important.

Best comparison i can give you is the comparison of the GTM VQ42VHR vs my VQ41DE. Similar displacement, same CR and practically identical FI setup, however i opted for HFC and smaller exhaust for noise. The DE made 512/395@9.4psi while the VHR made 546/411@11psi. Without the HFC and smaller exhaust i made 20/10 more. As you can see practically no difference and my cams have an extreme amount of overlap. Cam phasing/timing is moot since both setup have their advantage and disadvantage. You can also lookup the vortech kit on the DE vs skillen kit on the VHR (both stock), not a dramatic amount of difference in the net result either.

As for this build, granted that they don't run into any slippage problem then i don't see why they won't be able to hit 20psi. The stillen setup as far as minimizing pressure drop is very efficient. But like someone else mentioned, the air to water might be the limiting factor for maximizing power. E85 should help though, so lets see how it goes. I would also love to see the V7 dropped in. The 370z has more room so it might be possible with not a lot of work.

thats what i mean its before cams. The vvel's "profile" is already at what hr and de race cams are at, the hr is somewhere in between the two so if the supercharger made 21psi on de stock cams, putting it on an hr means more overlap and less boost do to a bit more wasting, and a better breathing engine. You can cam any of the motors to do the same thing as a vhr, but that isn't the way they come. to really make use of a built engine the guy is going to need a T trim or v7/v4 whichever fits easier. If they get 600hp out of the modified v3 they could get 700 or 800 out of a v7

Oh and a turbo reference doesn't translate over to superchargers all that well. A turbo is much more tolerant of excessive overlap than a supercharger is.

Not sure exactly how much overlap the VHR has since i have never seen the cam spec card nor do I claim know exactly how the VVEL black magic affects the cam for that matter i'm not even sure if anyone knows for sure.

I didn't make any reference to turbos. A SC is more like an NA compared to Turbo and NA, when talking about cam profiling. The first you worry about blow thru where as the latter you worry about exhaust gas making its way back into the engine.

Sorry for the off topic conversation.

You seem to know a lot about blowers but this is a HR not a DE. Why don't we just all wait and see what magic the mad scientist and Jtran come up with

I thought we covered this was a HR build days ago...

Im just trying to have a discusion to see what they did to improve it, a little background on the platform and possible future improvements. You know put some usefull stuff in here. And exactly my point its an hr not a de so it will run less pressure than the 21psi of the de with the same mods. Hp could be more than the de but same blower spun same speed will make less boost on an hr. If they are spinning it faster, the question of the pulley size, and how much overspeed it is, as well as how long the blower will last at that speed is raised. If its 15k over speed, depending on how much redline it sees it may make great numbers, but it could also blow the charger much sooner. The discusion right now is what the shops thoughts on that are or if it isnt a concern to the customer, maybe its a case of if it blows well just change it out. If that level of speed is safe then that would be usefull info. No one on here likes to have technical discussions aparently, its like everyone is just waiting to hear what some shop does next instead of asking questions posting info and trying to learn something.

Man....just close the thread already....fuk informing the community on credited shops and professional racers trying to expand the vq platform! Internet penis is getting 2 large for this tiny thread! Google it later because that's what makes everyone knowledgeable now a days anyways.

Don't do that. Some of us just want to see cool builds. This is a cool build. We can all say whatever, but at the end of the day that car is going to be a ******* animal. A lot of power and the response of a sc has got to be a whole lot of fun.

O&G guess we ain't smart enough down here in Texas for these here builds....


However I vote with Chuck, so in for the final results!

Come on man.. Just add them to your ignore list. Please don't let a troll cost the entire community, we are not responsible for their actions lol
