I feel the same way about boats. The best boat is your friends boat.

With the newer turbo kits...SOHO motor sports ...royalty performance new twin kit.. boosted performance kit ...lag is almost non-existent ... isn’t really a on and off feel ......lol it’s always on

That is not true. I have had both on my car. When a turbo doesn't hit till 3200 rpms there is definitely an on or off feel..100%. When I would shift there was definitely lag in my response with my turbo.

With a Supercharger there is literally zero difference in 2500rpm to 3500rpm as far as a "surge" on power. It's perfectly linear all the way to redline. It just keeps building boost gradually instead of it hitting all at once like turbos.

Turbo - max boost at 3200rpm
Centri SC - max boost at 7500rpm

Explain how a turbo isn't on or off?

108??!! That’s incredible. I had no idea, seriously!

This is like finding out about masturbation for the first time again....

But, legally, most stations can run as low as e72 which is going to be lower octane. Fortunately for me, there's a Propel station close to me that has close to e85 according to my ethanol gauge. There's closer station to me that can go as low as e59 according to what they have printed on their pump. I don't use that station.My car made 167whp more on e85 than it did on 91 octane.

Now, about your masturbation issue......

I find this incredible. Why am I not running corn oil now?

Yes. You don't see this mentioned much, if at all. Ill add that it's probably the TQ that needs to stay in check. Especially low end TQ. This is what makes the centrifugal SC nice. TQ only increases as revs increase, and even at ~600 WHP, are typically only making in the range of 425 WTQ at redline. But to your point, 425 from a SC is not as safe as 425 from a turbo as the engine is working harder to get you that amount of TQ in the SC engine.

I went with Topgunz, he's the most active and responsive of all the kit makers.

As a side note, I just sent off my Motordyne headers to Swaintech for their Whitelightning ceramic coating.

I really suggest you get that narly, fungus nailed big toe out the rabbit hole. Sometimes it is just no fun at all.

I’ve been following your build.

Remember that running corn (ethanol), you will burn approximately 30% more fuel...resulting in suck mpg...but the ethanol also keeps cylinder temperatures lower than gasoline does.

Hit Jon up @Z1...he’s in your neck of the woods

You can install their 400hp upgrade & then add JW2 exhaust cams & then upgrade fuel system for e85....could end up with some pretty good whp numbers & still be N/A

Sounds like you’re in need of a Turnkey job....Spooler mentioned SOHO, as he has a nice single turbo kit; unsure total cost or installation time & Z1 could install & tune whatever you wanted.
Heck- you can tune in a 50-100 NOS shot; for a quick blast every now & again

Maybe my wording is in accurate ....but at 2500 rpm on a supercharger there virtually no boost ... it does build evenly through out the rpm range which is smooth and strong and yes 3200 rpm on a turbo is when boost comes on ....but ... it you are running the car hard are you really under 3200 rpms when you shift ..no you’re not so where is the lag when you shift above 3200 rpm it’s just a increase in boost/power which is more aggressive ....but I would look more closely at a supercharger boost output at 2500 rpm and compare that to the stock engine out put ..very little if any difference ...in a larger v8 motor yes there would be more of a noticeable increase at a lower rpm.....and when I referred to having both I wasn’t meaning at different times on my car I had two cars with both at the same time and believe me I compared them closely back to back to decide on which to keep ...comparing my supercharger dyno 3k rpm was only 1lb of boost sooo at 2500 rpm more or less nothing

I guess more accurate way of putting it would be in a supercharger you can floor it and have a consistent increase of boost .....but in a turbo if you floor it the boost increase can be instant to max ...hence the sudden “on” feeling ..I have gotten use to controlling it with the pedal ....and for his needs the supercharger would fit him better

While I agree with you Jinxx, for what he wants the centrifugal is his best bet. The linear power delivery will be more predictable when his wife drives it.

Agreed

TopgunZ · 07-13-2019, 11:44 AM

I believe you stated one thing in your first post, then contradicted it in your second.

You said there is no surge initially, now said it does.

I was the one who said I had both kits.

At any rate, I agree with your second post.
