I don't think any "haters" thought that the X wouldn't be as responsive to mods over the IX especially when Vivid did their first tests. Everyone already knew that the car was running way too rich.

I think the big question is: does the motor give more gains with similar tunes? In other words, give the car it's AFRs of 11s and give it the timing that it's comfortable with. Do the same on the IX - both bone stock. Then start modding with intake, exhaust, etc.. Will the car - in EVERY scenario - make more power? I stress every scenario because the IX could be more restrictive with some parts than others (and likewise to the X). If I give a well tuned IX an open intake and then tune for that and it yields, say, 10whp.. then do the same thing to the X, will it yield say 20whp?? Everything else being EQUAL?

Here, better question. Why does anyone care?!

This is so 13yr old it's rediculous. Your right Boostez, it's not "haters", it's people wanting to believe they have the best.

People are afraid of the new and unknown so they shun it. It's retarded and child like. An Evo is an Evo. It looks different, so get over it everyone!

Yes on all accounts.

But you haven't tested these scenarios!

Your comparison of the X being MUCH stronger than the IX with only catback and hi-flo cat isn't big by any stretch (difference of 27whp/15wtq if you take the high numbers from your runs on both cars).

With actual tuning, the X has already made more power with just a simple catback and a free flow cat than a tuned IX was ever capable. Even when running no cats, full exhaust, intercooler, stiffer wastegate spring, etc,. I think we already have a winner, no?

Of course, it is still unknown as to whether an internally stock 4B is capable of "reliably" supporting 500+hp like the 4G can on race gas. But I think that only applies to a few % of the current and future buyers. The vast majority will be happy if they can reliably make 100-125hp over stock, on pump gas.

That depends.

Pardon for my skepticism, but you must understand borrowing another 25k (with a trade-in) and then another 2-3k in mods just to get up to the same level (or 30-40whp more) of performance to a mildly modded VIII/IX is a hard pill to swallow. I need more testing results from other vendors.

The purpose of this thread is to present testing data. Not to give you something that you really want to hear

Dude, the IX already spanks the VIII. To compare a VIII to an X is really no comparison at all. If I didn't have as much time and money sunk into my VIII, I'd trade it for an X in a heartbeat.

Amazing the resistance is to test data, eh Shiv?

Shiv, I am really impressed with the results so far. Did you ever figure out why the car wasn't pulling timing when knock was detected? It's awesome what you're doing with the car, though, and can't wait to see what the dyno numbers are.

Great job Shiv, post the dyno graphs!

Most IXs are stronger than most VIIIs. But some VIIIs are just as strong as IXs And at the end of the day - they are pretty much equal with full bolt-ons..

That was the missing link. Thanks for clarifying.

Turbo is running completely out of air so 55whp still missing which is a LOT.

I would say that max is around 350 dynojet whp for Evo x turbo.

They don't have engine management yet over at AGP, so don't sell the car too short yet. This is the first Evo X tuning thread. AGP is making all that power with bolt ons. This car is making all this power with minimal bolt ons and tuning.
