Okay, I ragged the engine at 420whp every day like I stole it. I knew it would not hold with stock internals. Oh well, I dropped it off at SGP today for a full long block build up. Everything added will keep me safe from 500-600whp. I will be sticking to around 500-550whp to make sure all is well. I will soon be joining the ranks of the 500+ crew. I could obviously go for more but there is just no use at this time. Pics of the build and charts to follow.

 

I would be interested to know what it looks like when they tear it down in regards to wear. How many miles did you put on it at 420hp? Did you run into any problems or are you just playing it safe? I am asking these questions because I am trying to determine what is maximum safe output for a stock Z. I plan to get a turbo on mine soon and want the most bang for the buck without risking the motor. I drive my ride hard every day so I want a nice reliable safe setup.

 

Didn't you just get the Twins installed recently? You already blew it?

 

If you drive it as hard as I do which is pretty much constant redline, then I would get a TT of your choice and keep everything around 300-350whp. You would want to get all of the "safe" components in order to do this but you should be able to put 10's of thousands of miles on a TT at that range. I was not necessarily in the safe range on a stock block for someone who really jumps on the car constantly. I knew it would go. If you don't want it to blow on you, I would take care of the intake flow, fuel flow, exhaust flow, and a good tune at 300+. Thanks

 

Congrats!! I am in the thinking process now if i want to build or not!

 

Yep! Great tune, just too much stomp time. I drove the car as hard as possible from light to light and even worse on the freeway. You talk about fun, but you have to pay for it in the end.

 

I did the exact same thing to my car and other guys consistently drag their cars as well. I put 10k hard miles in about 3 months also. Hmm I find it strange....good luck with the new block..

 

It's all about the engine manufacture's tolerances and how close some engine are to those tolerances. Some last better/longer and some do not. There is no science, just the fact that the tolerances win/loose.

 

I guess that is possible...I've never seen a car at 6 psi put out that kind of power either.

BTW your car looks really good and is super clean. I don't really care for bodykits at all...looks great the way it is

 

The race shop is not real sure why it produces those numbers at such low boost. Just hope that continues as I move forward. I appreciate the comps on the "clean look". It is what I like. It really works for me with these cars. I have seen some of them go from nice to rice. I am not into that. These cars are literally taking most "muscle" cars for a ride. I don't think they need to look ricey...

 

I know this has been said before, if I just wanted to get a TT plus install how much would it run... Wouldn't want more than 350 rwhp...

 

With good tune, you are probably looking at from 8 to 10k for a basic setup without radiator, fuel pump, injectors, clutch&flywheel, exhaust etc. If you already have all that, you would be looking at 8 to 10k installed by a good and reputable shop.

 

If you are just looking for 350whp...then Id save some serious dough and get a Turbonetics ST...should cost around 6k total

 

^---That is the one I am saving my coins for. Should be plenty for me...

 

Might be a bit offtopic....

but since you have a 35th anniversay...hense the revup motor...

did you/your tuner having any issues with the engine mgmt tuning? and do you think that might have had an issue with your possible engine failure?

Im just trying to gauge the results on FI-ing a revup motor...

thanks

 

I was wondering the same thing actually. There seems to be more revup engines blowing than the older ones...

 

i got a question since you have a Greddy TT kit . you think i should just run 6 psi? on a stock motor? im just wondering cause im installing my Greddy TT kit on monday and was wondering what boost should i be boosting. 6-8psi?

 

People seem to be pushing the rev up motors harder and the numbers being produced prove that. They create more whp at low boost but still have stock internals. Hense, the blown motor.

 

what exactly went wrong.. your scenerio loooks exactly like mine.. i was running around on 420rwhp beating the shiet out of it and the all the sudden one day "clank clank clank clank clank" ****! LOL ended up being a rod end bearing failure.. did you do the same or did you actually throw a rod?

 

ohh and i have the rev up motor too
