which fuel pump? also what to use for more spark?

[moi]

Hi guys, need recommendations for fuel pumps which can be fitted in tank to replace existing pump and must support 500hp@wheels (not at engine). Dont want to go external setup.

Also anyone here run an aftermarket ignition setup for stronger spark? If so what components/brands would I need. Running Autronic SMC ecu.

Thanks.

Nothing will 'bolt in' to your tank to support 500hp atw .. that's quite a target by the way. You could put an 044 in there with a bit of work, but even it would be borderline.

If it has to stay in tank, think about mounting two walbro pumps next to each other. It'll require a bit of work, but it's all pretty straight forward. Don't forget to upgrade your fuel lines from the pumps all the way to the rail either.

Spark wise, you've got a shitload of options. Personally, I have individual bosch coils with built in ignitors (same as LS1 coils). They've got no problems with my car supporting 435hp atw, and I've seen the same setup used on a car making over 700hp atw with success. You should be able to use the same with the autronic, though I think you'll need to buy the dwell board.

Im not too sur but maybe a sard in tank pump, but I dont know what hp rating they are other than that i would suggest that you will have to go out of tank set up.
The ignition side you will need to run an ignition amplifier,Im running a MSD DIS-4 unit and have been for 7 years.I was running the standard coil pack with that too
