I am curious to know how much boost you guys think we could safely run on both MS109 and a 50/50 water-meth kit under the following scenarios:

1. Bone stock engine
2. inlinePRO 3mm headgasket

I know that there are quite a few people tuned on race gas and a few on water-meth, but I am not aware of anybody running both at the same time. You might ask me why somebody would want to do this, and my response is that I believe you should be able to safely run more boost when using both of these items at the same time instead of only using one or the other.

Thanks for your time!

 

The reason you don't see people doing both is because you just don't run both . You run EITHER race gas or Meth, not both. Your not going to see any real benefit from running both.

 

Can you back that up with some facts?

 

You don't think you can run more boost and timing by using both products at once? I think otherwise, and will be on a mission to prove you wrong.

 

The MS 109 (109 research octane, 101 motor octane, R+M/2 = 105) should allow a couple degrees advance and the water-meth kit should also allow a couple degrees. The only way to proceed is on the dyno under the care of a master tuner like Church or Mase.

The bone stock engine will have problems above 15 psi if used for any length at all. With a 3mm headgasket you should be able to run 22 psi IMHO.

Some individuals have blown up the factory bottom end with less boost so be cautious.

The pistons have inadequate lands for the rings when using high boost. That combined with the fragile hyper eutectic pistons makes the engine failure prone.

 

Not as a DD, but on high boost with water/meth injection my tuner felt 26psi was safely doable on my setup.

 

More timing...and more boost.

I only have Shawn tune my S2000. He last tuned it last year and we had problems controlling boost (wanted to exceed 13psi) so we stopped the tuning at 7400 RPMs. The boost control issues have been resolved, but my S2000 is down hard right now because it doesn't have a rear drivetrain (upgrading to the R200 kit). Also, while my S2000 is down I am sending the head to Laskey Racing for their Stage 3 job, the intake manifold to you for porting, weight reduction, and polishing, and the TB to PortFlow. The engine, which flows very well stock, is going to flow like no other!

 

How much power did you make on that setup?

 

Iv made 497rwhp @ 24psi, but that was without the water/meth injection setup. I never had a chance to fully tune/dyno my car with it. My cars been down waiting for my InlinePro block to be installed. Im hoping for sometime next week everything will be done.

 

with the car down and motor in pieces, why not just sleeve the block and put in some 9:1 pistons? i seems a waste of time to put the motor back together just to have to take it apart down the road from pushing it to the limit.

my 2 cents, but invest the extra money now and have it strong like bull.
