That clutch will likely be insufficient to hold/launch with that kinda power. I don't have near 800 as of yet and I have this clutch.....granted older unit.....but I'm slippn in mid to upper 4th. I am also seriously considering a complete r154 freshen with all Marlin Crawler products and I now know I really need to build a stronger diff to be safe with my power (broken diff can be real bad) so it is time to consider a TRD rear. The clutch is going towards a twin or triple. I already have strengthened rear suspension components.
Every link in the chain all the way down to the very tires themselves have to be factored in now. And then stickier tires then stress the whole setup all the way back again right back to the motor. I mean sure my diff may hold for another year, it may not. I have had to plan to replace before failure as my power levels climb.
I personally feel that as you cross the 450 mark the next 100 gets much more difficult and likely to fail some part.........after that the next 50 is harder yet to achieve without breaking/failing.....now we are at 600........the next 25 becomes even harder yet to hold without issues. And so on... This is why the average number of I6 built motors.....7M/2jz/1jz whatever up above the 750 mark is extremely few and far between. And I am willing to bet those guys that are up over the 750 and in the 800 level break far more often than you would imagine. To them they know they will, they accept it and they are not really all that surprised when one of the links in the performance chain break......It's an accepted eventuality......over 750.....things will break......it's gonna happen
It's the older brighter bulb shorter duration situation. Yes this can be resisted somewhat with better/more expensive parts but there are limits. A 750hp motor is not going to be a trouble free not a worry in the world daily driver that is very likely to reach the 150,000Km mark.
With a GT45 turbo I think your gonna find you need a shot of NAZ to spool that bitch for decent response. And here again, this isn't gonna add to the life of your motor as I am sure you know. I just think a 800hp mark is truely a amazing amount of factors coming together that is not easy to achieve nor something to be lightly undertaken. You very well may be one of the rare people that get there and can afford to break things along the way while getting there and continue to afford the budget of staying there. And if so, you most certainly have my respect and you will without a doubt have the respect of many.
Just realize.......we all want 800hp monster daily drivers that can do it for as long as a stock setup.....but along the road to that goal realistic expectations change this and if you can choose the most realistic goals for your particular life you can then save money by most realistically choosing components once as you go and not getting more than needed or completely wrong items along the way.
Duane one of our own here recently graced the pages on Import Tuner with a legendary 7M setup. We all knew he was a titanic MKIII power in our small corner of the world but little did we realize he was in the godly stratospheric 1000+ RWHP level.
I am willing to bet my spare turbo that Duane did not get there without breaking, busting, swearing, spending while learning what it took to get there. I can also assure you that he does not expect to get 150,000 on his car without maticulous upkeep and even then he is aware he's going to break things before then.
Saving a buck here and there did not sit as a priority in his quest to reach these goals. I am sure his complete MOTEC setup was his pick because of it's low price for instance. Most MOTEC setups I know of are worth more than the average entire nicely built MKIII altogether is worth.
Just food for thought. And I am by no means prejudging you and saying you are not another Titan in the making. Who am I to say, I don't know you, I'll be the first in line to show my respect if you are. In the meantime, I'll hapilly help you out as best I can as many others here will also. Thats the great part about this community.
Just be sure of what your REALISTIC goals and expectations are plan for that goal and be aware of what that will likely cost you in time money and for sure the odd hard lesson.
