hp/tq/ and 1/4 with a 76mm/78mm turbo

[DETROITMUSCLE]

Go with an external pump and sump the tank. Not a fan of dual in intake pumps at all- kinda look at it as the "hack" method

How are they any different than your twin pumps, all twin setups have the same cons but I don't find them as being a "hack" job, everybody works on a different budget.

Mike, another option I'm looking into is the DW300 (320lph) with the FPWK-017W hotwire kit from Racetronix. This pump is rated at 870 crank hp N/A @ 60psi and 13.5volts. According to my calcs it should put it around 760-780 hp with F/I (depending on your boost) or 650-665rwhp. This is enough for my setup but I don't know what your goals are...

cons: You need to modify your stock bucket
pros: No worries about a pump failure causing you to go lean, no hobbs switch, can be done for around $230

If you are planning on 650+ rwhp I would suggest the Lonnies Double Pumper as others have suggested.

Dave - the turbobuick guys like the deatschwerks pumps. They've also been using the Denso supra tt pump, and the intank bosch 044.

To bad the zl1 fuel bucket wouldn't fit

I was thinking about running a DW300. You have to modify the bucket though?

Twin 255s are a proven method and probably what ill do

Jonny said it himself, a sumped tank and big external is better.

If you don't have a budget for a nice external setup then that's one thing, but don't kid yourself and think that an internal setup is better than a complete external fuel system.

Also don't come crying when one of those piddly 255 pumps fail and you go lean and your motor leans out.

Correct, I had a sumped tank and external 4303 for my car. However the cost of this set-up was far greater than a double pumper set-up. Just depends on your goals and budget. For Mike, a Double Pumper is what I would recommend. The cost of sumped/external, its capacity, and it's louder noise are overkill for this project. Double pumper will do the trick just fine

I'm not sure how the older ones work but the 99+ tanks have an internal bucket which is filled by a venturi system off the main fuel pump. The only aftermarket pump that replaces the venturi is the racetronix 255 but I already have that and it's not enough. No matter what I do I will need to modify the bucket myself to eliminate the venturi (and drill holes in the bottom of the bucket) or send it out to Lonnie's and pay $600 for a dual setup which is more than I need. Lonnies has been proven to be very reliable but anytime you add additional pumps and switches there is always the chance of a failure.

If you are interested I can get you in touch with someone who can source the DW300 for $145 shipped.

Yes, that would be your IAT sensor, no relation to speed density. For speed density you will not be using the MAF

Ok so keep my sensor?

Yes. You will still need it and use it.

Yes either that or you can buy a threaded sensor and have a bung welded to the charge pipe.
