why hasn't magnusson released the 2650 that is supposed to be so great. we heard about it several months ago, i just called and they said still not ready to be released. anybody with any insight would be greatly appreciated. i really wanted to stay top mount but turbo is looking better. thanbks, joe

All talk its on two cars only Pro Charger is sounding better everyday.

I'd call up WeaponX. They posted they just got their test blower last month and were working on a few areas it could be improved on. His thread said they might have units in this month to ship.

So thankful I didn’t wait and went F1A-94 plus Crawford Racing Holley port injection with boost control using precision wastegate. Car turns more heads and gets so many complements on how insane it sounds. Every single person who hears it says man wth is under that hood! I pulled hard from my buddies 2015 Mclaren 650 car is ridiculous fast and so streetable. I can’t quit driving it!!

It's quite disappointing really... Between the 2650 and the Whipple. Im sure 2300 owners are content as are the PC guys.

I couldn't be happier with my 2300 E force, easily can make more power then the stock pistons or fuel system can handle.
Maybe the OP is looking to build 800whp+ setup.

i was really wanting to stay top mount and push 1000 plus rwhp

At this point I guess I'll be happy and place an order for the heartbeat 2300 until I hear otherwise. If it can support mid 800 wheel without heatsoak I'm happy.

hogurt

it can support mid-800’s with ease. But you will need to have the right supporting mods. Fuel becomes a problem again over 800whp.

I see more and more that Whipple is the way to go since they have revisions for port injection designed into the blower. This eliminates the said fuel problem.

There was talk of some fitting the LT5 blower on a ZO6 but it’s gone quiet on that as well. Kong have just finished the LT5 porting program as well.

Mikec7z

agreed.

I think chris crawford had told me a while back he had successfully put lt5 blower on a ctsv.... but no vettes yet.

I think that there is a lot that goes into tuning the things.

If you dont build a motor first you are playing with fire! I learned the hard way.. now building a full tilt race car..

Mikec7z

what part of the z06 motor would you say is the weak link up to 1000hp and big torque?

I have heard the engines are pretty bullet proof with just a few minor things like ARP head studs and maybe some upgraded valve train, but thats it.

What is your advice? what failed on your motor first?

acz06

Spun a rod bering.. made 900 rwhp full e85 17 pounds.. f1a94.. the lt4 is definitely not bulletproof.. there been many having the same issues..

Mikec7z

so if you had it to do over again, would you need a whole new crank, or just better bearings?

acz06

If you are going to do a big hp build.. do motor first.. you will get people on here saying cranks never fail.. blah blah.. if you are going to do it.. do it..

I sleeved my block.. will be a 418 stroker build.. winberg crank.. Dyer rods.. CP pistons.. going solid roller cam.. edelbrock heads.. and maybe move to the f1x..I have a fore triple with 1050s and a motec m130.. may upgrade to 1300s.. I am still using DI.. rps triple.. 15 inch conversion.. big builds are intense..lol.. I am hoping this is one of the fastest m7s in the country.. we will see..

Build your motor for a big blower.. u will have more piece of mind and confidence..

Mikec7z

thats strange that the bearing failed for you. What else then failed as a result? did piston hit the valves?

Best closing quote ever!

I get that, but to me it's smarter to just wait until the motor fails or miles get up there. I have beat the hell out of my F1A-94 + Port Injection (stock LT4) on several tracks now (road racing) and street, not a single motor issue. In fact I hydrolocked it 3 weeks ago at Daytona having a port injector get stuck open (the motor didn't have a single issue). So sure motors fail, even stock ones do. Pay to play. But it's nothing to drop the cradle and pull the motor. Soon as mine goes, will take care of what it needs (used parts are even available now) with a better build on the bottom/top end. To do a procharged or PD blower wth port injection from the ground up is complex. I did the entire thing myself bullshit if you say otherwise. Lots of things to do and can go wrong doing it from ground up. Would I want to throw a motor in when I have a perfectly good low mile LT4, hell no! Why? Why add another $8-10k when you simply don't know it will fail? Keep it 1000 horse or less there are PLENTY holding up. Of course the bad stick out. They always do! No one reports the good. There was a guy at Daytona that had a procharged big HP build and has tracked IT HARD for years now. I saw him do 190+ on that bank doing 30 minute sessions (6 a day for TWO DAYS!). His car held up pushing it that hard for years now tracking it, with only a CAM + valvetrain upgrades, NO bottom end work. So I promise you that there are still quite a lot of stock and mildly modified LT4 motors out there making big power and beat to ****.

This **** ain't cheap! Nearly $40k in my car now with wheels and wrap on way not to mention the carbon **** I have ordered. If you have unlimited funds, sure, go for it. Let some shop do it. But I did mine alone on a 2 post lift it was a lot of work with a full time company to run. If I had to pull the motor and do that on top **** it would take me a year to complete! :-)
