It's pretty big sir, better check the dimensions. Rear of the car would be no problem though.

I'll have to look into that.

what kind of power levels have other people attained with similar mods?

Utterly maxed we've seen a X hit 400tq on stock turbo on your dyno but less than 400whp. I assume you do not have a tubular or cams. It might be a good exercise for you to stay on stock turbo until you really max things out. There are different ways to do that. Kracka is focusing on FMIC/piping/TB instead of cams/exhaust mani right now.

I wish I'd run my car when I was 360tq/340hp at DB. I suspect it would be in that 400/390 ballpark.

Yup, I've been sticking to mods that basically have no drawback. After my IX I decided to shy away from cams and a lightweight flywheel on my X. So far my fairly basic mods have been good for 360whp/380wtq (93 octane pump gas) on Cobb's Mustang dyno.

-AFE/Perrin intake
-MAP o2 elim dp/ETS testpipe/Cobb catback
-ported/coated stock exhaust manifold
-ported stock IM/TB
-Walbro 255 fuel pump
-Grimspeed 3-port BCS
-MAP FMIC w/Nisei UICP (stock LICP)

The only other things I'm considering at this point are a set of larger fuel injectors and a mild upgrade stockframe turbo (something the size of a FP Green or BBX-Lite).

Back on topic: Nice progress, Chris! I'm looking forward to seeing more product details/pictures of your testpipe and catback.

Looking good Chris.

I hit I think 393whp/400wtq on your dyno on my stock turbo E85 setup. Still stock o2/downpipe and FMIC.

I think 400whp/400wtq is totally doable but its running 30psi and lots o timing.

For 24psi great numbers...stock turbo E85 still my favorite setup!

What did your guys' boost graphs look like at those power levels? This thing tapers hard on the top end...

I don't have a boost plot from when i made the 393/400 or whatever on your dyno from the dyno day.

But this is the same tune from DB's dyno...this is with cosworth cams too. It had a perrin 3 port and the wga cranked down a few more turns too. This is about all you will get it to hold up top.

[v8klla]

Finally broke the 400whp barrier :) What's the stock turbo record? This was with the same mods and a simple fuel pump rewire which rectified the lean condition, EF2 testing coming soon!

Nice powerband.

Its always good to be on power for 3000rpm, or more.
