Thread: 400hp???

im trying to reach 400hp. last time it was dynoed it put 266hp no knock on a 3.2 pulley with a stage 1 intense cam with supporting mods.
now i did a 2.8 pulley drop with a full size intercooler, tog headers and full 3" exhaust, but, my fuel pump its dying, so lets shoot at 400hp!!!
my new setup:
-stage 3 intense heads
-stage 3 intense cam
-gen v with a 2.6 pulley (if its knock free)
-northstar TB
-phenolic intercooler (i live in Puerto Rico, pretty hot here, aluminum gets heat soaked FAST)
-60# injectors
-double roller
-4" FWI

i have a Lumina, hope to get some feedback!

E85 and a 150 shot of nitrous.

That stuff you have listed should give you 400 at the crank. Id say 350whp. If you have E85 in your area you could prob pick up another 30hp and run a 2.55 pulley.

... What kind of intake are you currently running on? You list a 4" FWI as a future mod... but your cammed and on a 3.2 pulley?

I would say between 325-350whp with those mods but you better be on a built tranny or your going to have problems. If you are wanting to pull 400whp or more you need to look at a turbo instead of SC application, but either way you need to add a upgraded trans if you haven't already. Ask BillBoost about high power builds and trannies, he's gone through 1 or 2 in his day lol.

2.6 on a gen v, holy geez, lolol.

Ramp up the timing and use a bigger pulley if you can.

If you are trying to get 400whp its impossible on a S/C build unless adding nitrous.

400 hp on a FWD... like a boss

i have a 3" FWI now, already made the 4" to go with the northstar set up.
im also building another transmission i have with all the tep goodies.
e85 is an option here, but i dont want to go as low as 2.55 since there is lots of humidity and heat here.
what else would i need to reach more than 350?

Isn't your N* 3"? I never paid enough attention to my N* TB

ill leave this here

Northstar is 4"

does the electric water pump really works?
does deletes like egr, bbv, evap work?
does a bigger exhaust work?
what spark plugs should i run?
i'm planning on running stock gaskets and head bolts.
should i go and get a belt wrap kit?

this is what i have already:
-a/c delete
-intense upper mounts
-solid (Homemade) polyurethane lower mounts
-2.6, 2.8 pulleys
-TOG headers
-PRJ Fuel pump & rewire
-full 3" exhaust
-stage 3 intense heads
-stage 3 intense cam
-northstar TB
-60# injectors
-double roller
-4" FWI
Still Need
-Gen v
-phenolic or stage 2 i/c for gen v (i prefer phenolic)

i wonder if a ported gen V would have any benefits for this.

No need to port a genV.

Maybe open the inlet to match the TB but that's about it.

I would add an 8 rib setup to the list.... youre gonna get belt slip with that 2.8
