Forced Induction Reliability

Dembflyr

I have 8000 miles of boosted goodness on my 09. Installed the GTM stage I at 12k miles. Stock internals and stock clutch. It's not my daily driver and I am not easy on it when I do drive it. So far so good.

I think you have answered your own question. 370z stock block was not designed to be blown. All components are stressed when aftermarket parts are bolted on. My stock clutch started to fail withing 8 weeks of going forced induction. Clearly longevity of motor will be compromised. If you can live with size of GTR that would be much better investment. Very few people are will to build 370z forced induction car properly. I count myself in that large crowd as I will run stock motor until it blows and they build up motor truly built to handle forced induction.

There is no definite answer to that. 500whp Though seems to be the upper limit. The problem is know one knows if your car was the perfectly spec'd engine/drive train when it left the factory or the one that just barely passed quality control. Same is true for a GT-R it can fail on the track unmodded too just like a modded Z could. Only thing is that the stock GT-R would be a warrenty replacement where as a modded Z would not.

When I go the route of FI I will probably looking at the 450whp area and that's what I am comfortable with. And I will have enough money on hand to replace it if it all goes to ****. The only thing you can do in the end is hope for the best and be prepared for the worst.

So far it's been ok. It is most definitely at its limit. I don't dare turn the boost up because I know it won't hold.

I went to the drag strip a few weeks ago and that's where I really noticed its limitations. The first couple of runs I wasn't trying to launch hard. Then I decided to give it one good launch. Not a good idea. LOL.

I will be upgrading it over the winter. I was going to do it this year but I spent my mod budget on the exhaust.

yea or you could be like me i drive my car like grandma and still ended up needing an engine rebuild when i was having the car dynoed for water-meth trying to be even safer.
maybe the car came from the factory with slight piston ring defects or maybe the owner before me was driving the car hard i dont know but this was my dd now i drive a crown vic while me car sits in the shop
only good thing and i mean the only good thing is when i am behind people in the crown vic they move over because they think i am the cops lol

25k boosted miles. went TT after 5k miles of owning the car. Just replaced the stock clutch a few weeks ago. I got a OS Giken clutch from GTM which I highly recommend. No issues so far.

If you plan to track the car, don't do it. You will just end up dealing with headaches one after another. Track driving is different than a couple runs at the street light against Vin Diesel. Buy a real car and call it a day

Wrong!
If you prepare a forced induction car it can easily be tracked, will it require more money? Yes, but it is doable.

If I am reading this right, your endgame is not performance on the street, but a lesser opportunity to have more authority on track days.

I'd hardly recommend it. You know (probably better than me) how important driving is on a curvy track to better times. (I am ASSuming roundy-round.)

If you want daily authority on the road, in excess, then yes, it's worth the trouble and the cost and the lessened reliability. (Every HP over stock lessens reliablity.) This curve gets steep up around 500whp.

If you want a dead stock GTR, it will beat the pants off of a modded Z. A bit more money, but then you are in the same predicament: I want even more...

It never ends. But we spend money and modify to create something different.

Reliablity is a mandatory speedlimit sign at the intersection of passion and performance. Who's looking?
