The trans is more likely the limiting factor more so than the motor.
I don't believe you have to start 10 threads, you have to reply 10 times to something or other. You're almost there.
This is good info, and don’t go Rev400 you can build the same thing for far less with aftermarket ECU. BOE stands for blowing others engines and their support is terrible.
The OP car is NA you're saying a standalone will make more power than a REV400?
No, I’m not saying that at all, and you darn well know exactly what I meant. With the same 1320, he can make more power and spend about 1/2 the coin.
Ok so standalone vs Fastworks tune got it.
Fast works is a joke. The end user cannot manipulate it. If you have the old software where you have the client that allows the end user to change it, then that’s one thing, but the days of sending in your ECU for a “tune” need to go away, as they’re just a “guess”, hence why so many blow up their rigs.
What aftermarket ECU do you recommend or suggest?
I don’t recommend anything as that’s for the end user to decide, but it all truly depends on how deep your pockets are and what tuner you’re going to use / have experience with. Me personally I decided on the ECU master full system and it has some teething issues, but so far the car is running fantastic, and better than it ever has and I have full control over every single aspect of the car from the engine to the dash.
Yes, you can get away with this for street use because you never push the motor hard for any length of time. If you tracked the car and I don't mean just drive it around the track, you would have most likely detonated the motor and windowed the block via a connecting rod. Most likely before that, you would have stripped either 3rd or 4th gear and also rebuilt the trans because you lost 2nd gear syncro.
Very true. I don’t know exactly what my HP is yet on my recent build, but I can tell you it’s way more controlled now and especially with the warnings in cockpit I’ve setup for knock and such to tell me what’s going on in the back with the rubberband.
Yes, the heat load of a truly tracked car are vastly different than a high HP street car.
R, The 2ZZ really needs to be tuned under prolonged high load to keep from blowing up at the track. However, just under 400 HP is achievable on an intercooled turbocharged street tune until your transmission lets go.Great info, and I can concur on the knock as since going stand alone and able to view my knock sensor logs and real-time on screen knock levels, it’s a noisy motor but once you get hammering on it, if you’re not using a high quality fuel, it’s very prone to knock and det. Have not put new build on dyno yet, but I’m predicting I’m in the 325-345 range currently on a conservative 75mm running MS109.OP has not asked any follow ups. So, I'll just comment on a few different viewpoints.
I as well as several other people I know have been running turbocharged 2ZZGE engines for many years. In the Spyderchat community you will find this is a very common build. Not exactly the same as supercharged but 250-300 WHP are pretty regular numbers. There are quite a few well past 300 WHP that are pretty reliable on the street. Again, that is for STREET use.
The thing with the 2ZZ is the knock levels shift with timing very quickly once load is applied. For example a couple pulls and the engine is fine. But, after 10 pulls the timing required to avoid significant knock shifts like 3-4 degrees even at low boost! The coolant does not show this at all and there are no significant sensor readings that would let you know the engine is in a more knock prone state (other than the knock sensor). From a controls perspective it looks identical. So, take a 2ZZ that was tuned on the street or transient dyno pulls and it will blow up on the track. I think this is a big part of why people say these engines don't do well on the track. It is also very hard to detect low level knock that causes hot spots because the engine is internally quite noisy. Additionally, there is a resonance right around 7k RPM that can potentially hide some knock as well.
