Hand Eye 8

Hi All,

I need your help. I'm trying to reach 600+ rwhp. I'm currently sitting at 555 rwhp. I have ported heads from AHP, Kooks 1 7/8 headers, no cats, corsa exhaust, Halltech 108 and B3 Cam from Race Proven Motorsports.

I plan to add the Fast 102mm Intake manifold and NW 102mm TB, but is there anything else I can do without getting a different cam? If I need a cam, any recommendations with good driveability? I want to keep this N/A.

Thanks for the input.

I would suggest upgrading your injectors and tuning on E85. You can gain an additional 30 to 50 rwhp over the 93 tune by simply changing your fuel.

Are your heads milled any, a nice bump in compression especially with e85 would def help.

This is my typical build on one making 585-615 rwhp.

LG 1 7/8 Super Pro Long tubes
High flow mufflers (Corsa, Borla, B&B, LG...)
ATI underdrive pulley
LG G7X4 or G7X5 cam
LG ported LS7 heads (11.3-11.75:1 compression)
FAST 102 intake
102mm TB
upgraded injectors
cold air intake


Depending on the short block when we start that generally will get them there.

I will say on customers doing the above with a stock intake and TB, you can generally pick up 20-25 with the FAST 102 combo.

Check out the "Mamofied" MSD and NW 102 TB combo from Tony Mamo.

No, just ported. Not milled any.

Why not your G7XX cam. That's what I used with all stated above and made 623/545 even with a stock TB. Stock underdrive and stock water pump. There was def more left on the table also.

If you milled your heads and FAST 102 on Pump 93 should get you that 600 number you want. If not, E-85 or Meth injection.

You most certainly can go with a bigger cam. You do loose some drivablity with the bigger cam (depending on the driver) or go smaller with the intake and TB.



Awesome results by the way!!

Seems like the Mamofied MSD is a good idea. I really wonder if I can get the 40-50 hp from this. I don't really want to change out the cam. Any idea of cost on milled heads? I love the drive ability of the car right now.

MTPZ06

If your are going to pay someone to R&R the heads just to mill, I'd say its not worth it unless you were also going to stab a new cam in there. If you can do the work (R&R the heads) yourself, then probably not so bad. If not, I'd say just go with the Tony Mamo MSD and NW TB, and get it retuned. That alone may get you right where you wanted to be with minimal money and effort for such a big gain. If you only get to 590rwhp are you going to be upset? I wouldn't be with those gains and just a MSD/TB swap.

Hand Eye 8

Agreed. 590rwhp or close to 600 would be great.

How is drive ability with the G7X4 or G7X5 cam. I know the G7XX is the biggest.

Thanks all for the input.

0Anthony @ LGMotorsports

Personally I just like the G7X4. It has a good sound to it, and with heads/FAST/102 combo the car drives very nice. Yes you can get some surging with it in 1st or 2nd gear and no throttle input but other than that they drive as OEM as you are going to get with a big cam.

The X5 you start to see more of a change in the power curve and really notice the car above 3000 RPM because of that.

It has been a while since I have driven a XX cam and C6 Curtis might be the better person to ask about that.


That all being said, it is going to depend on who is tuning the car too. A good tuner can really help drivablity on any cam change, and especially a big one.

Frans96ss

His cam is plenty enough. We have made 620+ on a regular basis with that cam on our HCI packages.

Rumpty Rumpty Rump....

Thanks for the info. My tuner did a good job with my set up. I'll see where I'm at after all is installed, but I'll give this info to my buddy that is looking.

Power are in the heads...

With your stock 11.0 CR, you'll be hard pressed to get close to 570rwhp.

I am not sure what are the exact flow figures of your heads vs. what exactly has been done to them, but if you want close to or 600rwhp, you may need to revisit them again while shooting for CR around the 11.7 to 11.9 range to run on pump 93oct.

Fueling will be key; bigger injectors should be in your recipe along with great tuning. You can get there on pump - much harder on 91oct, but much easier with E85, race gas or by implementing a pump/meth combination.

I'll be real with you, you're now sitting at 555rwhp and looking for 600 to 600+ to the tires...you will have to up the game to gain that extra 45+ rwhp no matter which fuel method you choose.

Hope this helps

Thanks,
Carlos
