After reading Rob!'s thread about hitting 750+whp on race gas and a 3mm headgasket it makes me wonder why nobody is running a SC application on a stock engine at max boost.

This has been brought up alot lately in this thread but still nobody has done it. Obviously the stock engine can handle 25+psi on a stock engine with or without a headgasket swap. Most SC kits cannot handle over 25psi. Im near my limit with the Nov1000 and personally, its not worth it for me or I would be doing it already.

The newer kits use a 1220/1220 SL blower (I think SOS, VORTEC, and CT Engineering all use this blower) Yet people are stopping at around the 13 psi area. Not sure if any of you know this but SOS has an option to sell a larger crank pulley that will net the 1220/1220SL blower more psi, a 3.0incher will net you 18psi (518135 has it) instead of 13. So basically the 1220SL maxes out at 18 psi. Pretty good compared to the 1000 that maxes out SAFELY at 12/13psi.

Also, what 518135 and myself did not know is that SOS also sells a 1200 blower upgrade. Its a larger blower than the 1220 and it can flow 100 more CFM at 22psi. (super high is you ask me).

I know most of you already are thinking "why is this idiot posting this information, we already know this!" But I just want to make it a little more public that these upgrades are available so maybe some of you guys will bite the bullet and push the limits!

 

i would love to see someone try that on a stock motor with q16.

 

Why are you posting this we already know that.

Just kidding...I'm kind of planning this for myself since I heard of the smaller crank pulley. I'm taking it a small step at a time since I don't have another engine sitting in my garage and this is a DD.

In a nutshell the only thing holding me back is the wife and my car is a DD. I'm keeping the car for awhile and plan on continuing with the SC for now so you may see some updates from me in the near future.

Thanks for mentioning the 1200 option. That seems the way to go...the 2000 may be too big.

 

i think it has to do with a conflict of interest. i switched back from my turbo setup to an SOS blower because i wanted simplicity. i also realized that moderate power gains were really all i was looking for. it seems that most people going the SC route are not trying for maximum peak numbers - so why bother using race gas with a blower?

there have been some enormously huge numbers floating around here on the boards - but that doesn't mean that making the most whp ever is going to make all of us happy. i am much more content making less power with my blower than i ever was making more with my turbo setup - the setup just didn't fit my taste.

something to think about

 

Good points. I don't plan on it getting so hopped up that it's all race gas setup.

 

what blower does krazik run in his race car?

 

didn't he also put down like 400 whp when people with the 12 psi pulley did the same? seems like running a lot more boost for no reason. not really worth the risk there. also the 600-700+ turbo'ed guys are all running race gas. but they can turn down the boost and run on pump if need be. if you have a scer car running race gas only and u run out u have to take off your pulley. seems like way more of a hassle to me.

 

its unfair to completely judge his car. that guy was on a dynojet. you hardly ever see CT/VT cars on dynojets. u always see the dynapack 450-500 dyno sheets.

also, i thoguht his was the 1220 SL, which is smaller then the 1220 non sl, whish is smaller then the 1200 that he shoulda bought. also, he was on a 9.8ish:1 built block.

i wanna see someone push the 1200 blower thats for sure

 

well got my 3.0 pulley then im done.honestly the ctsc with the 3.2 with 4.77's is a blast to drive few more ponies will just make my setup complete

 

I agree, its unfair to compare that engine. It is infact 9.8:1 at 18psi and a stock bore and stroke F20C engine, not a F22C...big difference right there. Its also a stock header/head/intake manifold and throttle body, not to mention the invidia 70mm header back with a V4 (which some people consider restrictive)

Alot of good points here... Some I already took into consideration...however, still...why hasnt anyone pushed the envelope yet? Seems to be the thing to do lately.

The SOS track car has 10.5/.8:1 with a 1200 blower at 17psi and made 450whp... Id say 500 is obtainable with a nice header and 22psi on race fuel.

What I want to see:
SOS kit with 1200 blower at 22psi on a F22C stock engine...Anyone willing to jump of that plank...?
