Mine was at stock pulley I think 8.5 psi and I think it because of the V3si the self lube one.

Oh yeah the self lubed models suck and seem to blow frequently.

What boost are you running on this HKS kit now? And why not go with a smaller pulley for 400+whp?

 

I am at 12psi now with the HKS supercharger I can go more but you would need to build the motor with sleeves, rods, pistons, head and upgrade with a return fuel system. I think anything pass 12psi on a stock block is not going to last very long. Also I would love to do it but it is a lot of money.

 

Which blower is this? I understand it might read low but is it reading 80-90 hp lower than most others? 12 psi SOS,vt,ct would usually be around 400whp.

Are they using the c38 blower?

 

HKS GTS7040 Which can handle up to 200-400ps

Most of them on 12psi SOS, VT, CT most of them are on a dynapack dyno so they read a lot higher since they are not using the wheels to spin the roller. So hitting 400hp on a dynapack is not that hard but a Mustang dyno would be a different story.

Ah ok did some reading on it. Same one evasive was testing right?

This blower can spin much faster without over spinning it? What rpms is it spinning at the 12.5 psi do you know? From reading it looks like 12 psi or so is close to maxing it out unless I read incorrectly.

 

can evasive can provide a dyno comparsion of these 2 kits?

 

Evasive has a very low reading dyno.
I've been in Randizzle88 car, and his car is faster than 324whp

My car full Race gtx3076 @ 16psi
Evasive Mustang Dyno


Autowave Dyno dynamics
Different conditions, but 72 hp is a huge difference

 

This can happen sure, but most of the issue seems to be with the optional self lube type blowers. The engine oil fed units in our experience are proving to be much more reliable. I had an old Comptech/Novi 1000 with over 100,000 mile on it before my bearings started showing signs of failure, and half of those miles were running near max spool and some towards the end were over spooling a great deal, which probably shortened the life prematurely. The self lube blowers contain a mere 4 oz of fluid, which to me seems like not nearly enough to keep the unit cool and maintain the integrity of the oil for proper lubrication. In theory its a nice idea to separate the engine oil from he blower oil, but in execution it seems to consistently be proving to be a poor choice for blower/bearing life. I am upgrading to a Novi 1200 unit and it will be a engine fed of course.

 

Is there any documentation from HKS on the max boost from this blower?
