EVOMS picked up my car today for the next chapter in the never ending evolution of mods. This phase will include, among other things, the following:

1. EVOMS forged piston kit
2. EVOMS sport exhaust camshafts
3. Port/polish/flow the heads
4. EVOMS high pressure head gasket
5. Bell 4.5 inch intercooler cores with custom end tanks and piping fabricated by EVOMS
6. Quaife limited slip differential
7. Strengthened/reinforced transmission (details to follow)
8. Michelin PS2s
9. Refinements and tweaking to the programming

The head gasket alone should give me an additional 95 HP (that comment was for Jean). Seriously, I am not expecting a quantum leap in power by virtue of these mods. Rather, the pistons and head gasket are strictly for reinforcement purposes. The head work, cams and intercoolers should provide some power gains, as should the modified programming designed to address my unique configuration of components. The LSD should improve traction, and the PS2s should improve handling in most daily driving scenarios (as compared to my Cups, which need to be heated up).

Todd estimates two weeks for the entire project. Thereafter, I have several runs scheduled, including a 900 rwhp Supra and a couple of S/C'd Vettes.

That sounds AWSOME

 

That's awesome Craig, can't wait to hear your impressions when this is complete.

Didn't you complete major engine work etc some months ago? If so why are you doing this again?

Cheers and good luck.

 

Craig,

The head gasket is thicker (about 20/1000) which will drop your compression by three points. I don't put any stock in that 90 hp number. I wouldn't expect any gain from a thicker head gasket. I know it is a strong gasket. I am utilizing one, but I am also cutting the barrels so as to avoid the compression loss.

If you are porting and polishing the heads you should increase the valve size. You can only flow so much air utilizing the stock turbo size valves.

 

Yes. However, several of the parts I am now installing were not available when I previously cracked my case (e.g., the head gasket and cams). I thought about doing the pistons the last time around, but decided it was not necessary. I have changed my mind based upon the amount of boost I am running. I wouldn't have cracked the case again just for the pistons, but the availability of the reinforced head gasket (likely my current weakest link) and superior exhaust cams pushed me over the edge. Moreover, I had to drop the engne anyway for the tranny work and LSD, so it was the right time to do everything. Fortunately, its only the top end of the engine this time around.

Chad, I was kidding about the 90 HP number (re-read my post).

The increased thickness of the head gasket is necessary in order to accomodate the new exhaust cams. Todd and I spoke about the slight decrease in compression. I do not expect any meaningful reduction in power and the superior exhaust cams will more than compensate.

Craig

 

Damnit, we keep going in circles, craig, my car is also going down for a cam, alky and some other tweaks. It should be done pretty quickly, though.

Who is the 900hp supra around these parts? I know Braddman from supraforums is local, or are you referring to Alex's car?

 

Craig,

CT makes a piston that has the clearance. We designed (mocked it up) it and I believe Todd has used it. It will clear the GT3 intake and exhaust cams. I am guessing the exhaust cam being used is the GT3 exhaust cam or something extremely close.

 

I was referring to Brad. His Supra is currently getting fitted with a new turbo that typically produces 900+ rwhp. Thats a lot of power. I may need a head start -- alternatively, we could start from a dig.

Let me know when your beast is ready.

Craig

 

Losing compression points will affect response time or lag. Not real bad but noticable.

 

Chad, you have a pm.

Thanks,

Craig

 

Damn look at you go!

 

Can't wait to see the results. Also, two weeks is pretty fast, Evo must know their stuff

 

Thicker gasket lowers headgasket and actually cause some loss in HP.

 

Craig, we hope to see you on March 11!!!
