Well guys long story I;m re-doing my engine and contemplating a nasty solid roller 8200 rpms hi compression 396 with 250 shot for an easy 700 rwhp OR a low compression motor with ati f1. What do I need to get the blower steup to around 700rwhp...how much boost? how much cam? I'm gonna be using FULLY ported trick flow heads. And I want the car to still idle REALLy nasty (lopey). Driveability is not a concern. So help me map out what I need.

 

If you want a really radical cam/idle go with the big motor and nitrous. You will need aftermarket engine management to do 8200 rpms - you list Fast so good luck and glad you have the money.

f1 will be just warming up to do 700hp. Generally boost and big cams don't go together. It can be done and there are plenty of high reving big boost motors. If you want to go with a big stall and switch to an auto and only drag race the car then its an option.

An f1 with really good flowing heads - say 320ish - and something mild in the 230 duration 650 lift range cam will probably only need 10-15psi depending on displacement and compression to do 700rwhp. If the motor really flows it might do so with even less.

Remember cyl pressure is what breaks parts. Boost is only the amount or resistance in the intake. I have seen 700hp 40psi cars and 700hp 4psi cars.

 

Ya I Love a radical idle, but I'll live with a tamer idle and the howl of an F1.

I was just gauging how "EASY" getting to 700 rwhp will be. I know that there are alot of supporting mods needed but my main concern is the heads and cam. I was that I can run a little more aggressive cam and have the lopey idle i desire and not blow all my boost out the tailpipe. I'm gonna have a good porter do my heads prob flow a realistic 310 easily. Oh and obv be changing pistons for idk maybe around 8.5:1 compression.

I know I said driveability is not a concern but I figured if I can have a somewhat lopey idle, a blower howly, 700rwhp and better driveability than a huge solid roller motor then why not.

 

You could buy my heads and shortblock and do it... or just buy my shortblock since you already have the heads.

Jerry

 

Actually have the shortblock just need to change pistons....have yet to acquire the heads LOL

 

Well hell, buy my entire setup then. Heads, shortblock and turbo system and there is your 700rwhp.

Then sell your motor setup and get some money back.

And the parts are OBO btw.

 

I made 700 rwhp 640 rwtq with trick flow heads out of the box only minor clean up and new hardware, a 242 246 duration 612 612 lift on a 114 lsa (selling this cam btw ) with a D1sc at 15 psi. You don't need crazy parts to make the number just a well put together combination.

Steve

BTW jrutland is a bad *** seller to deal with!

 

How did you like the cam? What are you switching to? Any idle vids?

I;m gonna be doing a F1a with fMIc and fully ported Trick Flows. I want to make 700 rwhp without meth injection

 

I dont have any idle Vids but the cam was awesome, instant power, great sound, awesome setup!.

I am going with a 244/248 652/652 on a 114lsa

 

Who is doing the cam for you? Custom or off the shelf? How much power are you expecting to gain with the extra lift? What kind of powerband?

 

Custom cam through amp performance there are several changes taking place I am looking to make 850-875 to the wheels with this cam afr227 heads edlebrock lt4 intake, f1a with a cog drive, kooks 1 3/4to 1 7/8 step headers etc etc...

 

Sounds kinda like what I'm shooting for I'm going F1a, non cog tho. I was gonna run the TFS heads tho. Any reason youre gonna run AFRs? What kind of pistons and compression? How much boost? Meth inj? FMIC?

Sorry for all the ? just seems like we are after the same goal and I GREATLY appreciate your input.

 

The AFR 227 heads begin where the TFS heads max out CFM wise. Standard valves are lightweight 2.100 intake and 1.600 exhaust,offset intake valve, they are just a much better head for similar money invested. you will pay $1400.00 for the heads than well over a $1000.00 to have the right port work performed so $2400.00 plus to achieve what these achieve for $2500.00out of the box with room to grow.

The motor has custom JE pistons at 9.5:1 compression, 20 psi of boost if all goes well with an Air/water setup. I am staying hydraulic roller as well

Steve

 

I'm wondering what compression ratio I should go with for around 20-22 psi and FMIC without using meth injection, I plan on getting a GOOD intercooler, the ones on ebay seem like they dont flow that good.

Hmmm def gonna have to look into those AFRs. I would DEF have lloyd or AI port them right away to the max.

I'm planning on doing a hyd roller now that I'm going FI, gonna do shaft mounts this time tho.
