My 8 trumpet Manifold Project.

Thanks for all those comments guys

Yep, I'm in that land down under commonly known as Oz, so time differences don't allow me to be online at the same time, .

I have no idea what the HP output is other than it boogies, although as indicated the wideband a/f gauge is showing the 19lb injectors are obviously maxing out at WOT.

But my US net buddy in CA has just taken delivery of some FMS 24lb injectors, calibrated Pro M Maf and also a 93 Cobra X3Z ecu and matching 73mm Maf and they're on there way. After the the 24's are installed I do intend to put it on a dyno out of interest.

However, being in a 4wd I purposely built the engine with low compression for several reasons and high hp was not the main aim etc but its stats are.

5.0 + 020", 8.8 compression, GT40X Turbo Swirl alloy heads with 61cc chambers, all intake exhaust ports matched, custom 1-1/2" headers, E303, 1.7 rollers, 73mm Maf, 70mm TB, 255lph pump, Malpassi FPR, and the injection as shown. I would suspect it should be around the 350fwhp, once the 24's are installed but I could be wrong, so any views would be appreciated.

I may consider replacing the E303 with a more appropriate cam later if the lope etc interferes with 4wd use, .

Comments on what would be a good replacement would really be appreciated.

I was interested in this guys comments about the Comp Cams nitrous designed cam used as n/a, particularly the street manners etc.

" if you want awesome low end up to 5800-6k use the comp cams nx264hr cam I am running this cam it is ground to preserve the low - mid end it sounds decent to not to lumpy but not stock either. And if you ever run Spray or super charger it is great fo that too. http://store.summitracing.com/partde...2D35-552-8 This cam has great street manners no surge no drive issues car runs perfect as it did stock.

However, on page 1 of the stats it mentions its not computer controlled compatiable yet if you click on "show all" it says Cam is designed to be computer-compatible with factory electronic fuel injected vehicles. so I am a tad confused, .

Obviously, I want to take advantage of the injection set up but at the same time would prefer good street manners, good mpg but a lope is not a problem

But at the moment with the E303 it does haul to the rev limiter in seconds and so so easy. It also has a bundle of torque and I got a great mpg with my former custom upper manifold and I expect the same with this set up if not better so any comments on the above cam or others would be appreciated.

Its in this,

I have two setups coming.

One is a Pro M maf calibrated for 24's with a set of FMS 24lb injectors that I can therefore use with my current EEC -IV ecu as the recalibrated MAF will take care of business

The other is the factory 93 Cobra X3Z ecu and its matching MAF. The Cobra ECU is supposedly factory programmed for 24's and I'm told Ford Oz used this ecu in a 93 model XR8 Falcon as it also came with 24's.

I would have thought either option would be fine but please let me know if either could be a problem.
