Thread: GTIR SR20VET Dyno Predictions: Going with VE Intake and Xcessive Plenum :)

Good guess!!

500awhp is my guess.

I think as long as you get everything set up correctly, the JWT program is plenty good.

People still use JWT ECU's?

hopefully the tranny end case doesn't go kaboom on the dyno...

oh God, here we go again, jeeze, Just because some people have had "issues" w/ jwt tunes doesnt mean everyone does. lol From what ive seen every single setup ive seen with a jwt ecu on has been rich, not lean.

JWT ecus work just fine. Again keep it simple and make great power all around without worrying about it. With a realtime ecu there is always that chance of error if someone doesnt know exactly what they are doing.

Anyways back on topic,

Im gonna guess around 500awhp at that boost level with the setup. Great flowing turbo, although i hope you have springs and retainers in the head and plan to rev it out more than 8k. With that large turbine housing your not gonna hit full boost till about 5800-6000 but it will hold full power well out past 9k if you rev it out to it. Simple setup, thats all there is to it.

Rev that thing out if you have the parts to do so. If not your gonna be stuck with a powerful but short powerband from about 6-8k if thats what you stop at.

People just need to lay off the back about jwt ecus. They have been used since the beginning of turbo'd sr's. JWT with an SAFC is Golden when it comes to simple setups that have worked great just like a Calum basic with SAFC and so on.

And before you say anything, Yes, I know, He wont make as good of power because he doesnt have a realtime that he can mess with both timing and fuel. lol. That is an obvious. But doesnt mean he still wont make great power. So again, dont take what I say out of context. Im using a Standalone myself and I know the benifits but this whole downplaying JWT and Calum basics is retarded. They do very very well for what they are and especially well with a SAFC on top of it.

You are right.

They have been used since the begining of SR time. Maybe that's the reason only a handful of FWD SR's have made big power.

Look at Fred Casey for example. Just image what that car would have done with a tuneable ecu. Not trying to argue about the same non-sense again, just would like to see the forum move away from all the bench racing, bandaids and theories and actually do shit right.

Everyone is chasing these big #'s and expect it to come with ease. We can all Just plug in, turn the boost up and go, while we wonder why turbo SR's can't even catch most honda's naturally aspirated.

We have a long way to go..

Again, I say 399whp. Especially if this car is in Jamaica, which I believe it is.

i say 399.5 jamaicans always round up

Jamie I feel you are correct freds car made 522whp at 32 psi. I believe that with a realtime you could have picked up atleast 40 to 50 hp and nevermind how that tune change could have affected the powerband. That's why I will run a aem in my car and I am gonna let Mr. Marsh work his magic.

You know us too well lol



I agree 100%

Your right Jaimie, most of the people that have been in the SR20 scene for the last 10 years have all settled with about 400-450whp i mean which in a b13 is enough to run low to mid 11's very consistently. Most people were satisfied or content with that. Being to go much further than that required extensive modifications to the fuel system, ignition system, a twin disk clutch which most people were too scared to run on the weak 5 speeds and so on. I found about 520-550 to be about the limit with simple chipped ecu, stock ignition, and a walbro in tank with all factory lines. With a properly built motor that can and has proved very reliable at least for me it was and can do 10's with enough seat time but your absolutely right, Most people just didnt want to push the limits and wanted to stay in a comfortable spot. And thats why the hondas are ahead in everything. Because they wanted more and more and wernt afraid to do so and use the right stuff.

Why do you think I went with a Standalone and CDI box, lol Cuz i wanted more and wanted to make it as reliable as possible and have control over everything that the engine runs on and with. Simple as that and make the most power I could.

Again doesnt mean we should bash jwt ecu's and Calum ecu's. They work great for those types of power goals. Again your not gonna have the most efficient engine compared to one on a realtime or standalone but you will still make great power and it still be pretty reliable.
