....I respect blackbenz but there is no where where the weistec is making 800hp on the m113k engine. Yes even if someone made a lot of power on m156 engine, that is a high compression 6.3L engine. Huge difference from m113k. The point here is so far, does the weistec s/c make power than the stock amg s/c on the m113 engine? It appears that at the same boost, but s/c's are similar in how much power they make on the m113 engine. It appears that the weistec s/c may make more lower at very very high boost level, unlike the amg s/c. This really seems to be where the benefit of the weistec might come in. But you would almost certainly need a built engine. It is not going to be as simple as slap on a weistec to an m113k engine akready running 200mm pulley and maje more power. I suspected this earlier. That is why when BIP performance where advertising selling built blocks. I recommended they partner with weistec and sell he built engine and weistec s/c as a combo.

these engines are very stout for a stock engine. about the most stout of any i have seen. if tune was kept conservative, i see it holding up to 700rwhp. just dont rev much past 6300.
i have seen bone stock ls1 truck engines run a drag season at 780rwhp!

A bigger blower is just like a bigger turbo vs a smaller turbo. The smaller turbo/blower will make power quicker BUT can't make as much power as a bigger turbo/supercharger. I've had big whipples and you have to spin them harder than a stock blower to make the same power but they shine where a stock blower has thrown in the towel. These blowers will run all day long at 23-30psi and that's actually where they like to be at (20-27psi). A stock engine will handle it with spot on SAFE tuning and not turning the engine hard over 6200-6300 tops. The rods are forged but have very small rod bolts. As far as comparing the stock blower vs the weistec I don't see how anyone could compare the 2.

To be fair, my GTI 1.8T had nearly identical sized rod bolts ( it literally looks like I can swap them, they may even be the same ) and I made 378whp and would spin to 7500rpm on a bone stock 1.8T engine and it never blew. Given that this engine was making 94whp per piston/rod...what makes you think the stock rod bolts M113 can't handle 750whp while spinning in the upper 6K's/lower 7k's?

I sent a stock rod to Oliver billet rods to have them test it. They told me 700hp and 6500rpm was what they thought the too of the "safe" limit would be and pushing that would be a time bomb. I also sent a rod to another big name engine builder (Chris Uratchko) and he told me the exact same thing. My engine builder also said he I was on a short fuse turning 7200rpm and over 700 crank HP. That doesn't mean as soon as you do it they will fail but when you have 3 very experienced people come to the same conclusion I'm going to believe them. I've dealt with Oliver in the past and they as honest as they come. I've had them tell me to use another rod because it was just as strong but cheaper and they Didn't see a benefit from running one of their rods.

rod bolts can be relatively easy to change by removing the oil pan. not sure about our engines though.

Gentlemen, just to clarify a few things so we can hopefully help out. There were a few members mentioning a max limit of the stock map sensor. This (and many other things) was rectified many many months ago when testing. Relative to our supercharger system, there is not a limit.
We test our vehicles and we advertise our figures in pretty tough conditions. This means hot water flowing in the intercooler, 91 octane fuel, a test car with over 100,000 miles on the clock, and very conservative calibrating. These are the worse case scenarios and we don't aim to cheat our figures by cutting corners.
The biggest difference in our opinion is that it is extremely challenging to make anywhere near 600 HP at the wheels with a stock supercharger system, yet it is extremely simple to do it with our system. It is doing it conservatively, and this is something that should be pointed out.
To make 800 HP at the wheels is very challenging, and will require a built engine whether it is being done with our unit, or a stock unit with spray as an example. In escense 800 HP at the wheels is 800 HP at the wheels and you will need a block, rods, and pistons that can support this. Not to mention many other parts as well that are much more complex.
Lastly, this is a new system and we expect many questions to be answered with time and use of the system.
Thanks guys!

Well said weistec!! Good thing I'm building another engine
another good point is how hard it really is to make 600+rwhp on the stock blower. It took me ported heads,cams,195mm pulley and race gas to get past 600 rwhp and I know I was right there about where the limits are for the stock blower. The weistec is just getting started at 600hp

Hey Weistec what were the iats before and after runs, if these were like everyday driving conditions(no ice, etc), this will prove alot on how effective this blower system is compared to the stock

dont forget on these big blowers part throttle and just creeping into boost a hair the car will be a total animal. 3.4 whipple on a shelby you have to peddle the car alot of times under wot. Just hang on and enjoy the fun.
