eyy,,,+++ me RIPRX7

Re: Rotary "Summer" Unit GB interest
 

Hi riprx7

you have to specify what you want exactly. Do you want just the Summer or HFS-6/HFS-3 + Summer...

1. Drunkengimp (summer+HFS3)
2. remydrm (summer+HFS3)
3. Snyrx7 (?)
4. trainwreck517 (summer alone)
5. MaD^94Rx7 (summer+HFS6)
6. r2omega (summer +HFS6)
7. FD-KAI (summer + HFS6)
8. RX72NR (summer + HFS6)
9. riprx7 (?? + ??)

Re: Rotary "Summer" Unit GB interest
 

Id like the summer with hfs-6, but if this takes to months get 20 people I think I just have to get the hfs-6. My car has to be ready in march.

Well we have to pass the word on as much as we can or else when we manage 10 ppl we get 2 summers each lol :)

1. Drunkengimp (summer+HFS3)
2. remydrm (summer+HFS3)
3. Snyrx7 (?)
4. trainwreck517 (summer alone)
5. MaD^94Rx7 (summer+HFS6)
6. r2omega (summer +HFS6)
7. FD-KAI (summer + HFS6)
8. RX72NR (summer + HFS6)
9. riprx7 (summer + HFS6)

It's good to see people with rotaries understanding water injection is the only way to make true reliable power ;)

Anyone in any doubts here is a thread (feel free to share and pass on) as to how well it works. Should be mandatory on all turbo rotaries :)

^ 8000km of running at ~500bhp level over 80lt of WI used ........ that is (3+hours) at full power setting. And my original engine is like new. When rotaries at this level of power life span can be measured in seconds and minutes (at full power output) this WI just shows again why its the best technology man has ever engineered for the internal combustion engine :)

Hey Peter, thank for chiming in. There are still a great deal of people do not what water can do for making safe power. You have contributed a great deal already on this forum, keeping me up at soem nights.

Can you share some of the experiences on the effect of running 100% methanol instead of water. Most people on the RX7 club forum run pure methanol, do you think it is unnecessary where water or W50:M50 will do just as well? I am not familiar with rotaries.

Hi Rice

thanks for that. I always read your threads and saw what you achieved on your site.
As you say there is only when way to go and thats with water injection.

it took me half a night to get to this point. Sorry if I am computer callenged but I'll bet I can change a tire as fast as anyone or better. I have said in more than one post I want one of these summers things. As for the 6 or 3 I guess I.ve got to go with the 6 . So now add me to the group. One last thing, Richard I have had the pleasure to read your posts. The have beeen very educational and I think we could definitely drink a glass of bitters together and talk.

Re: Rotary "Summer" Unit GB interest
 

Thanks Henri,

Yes I not only believe so but unlike most I suppose I have proved it over the last 15 years of consistently using water injection on all kinds of rotaries (and lesser internal combustion principles!).

(This all has to be given some context)

I make the same power (with proven durability) ~500bhp
Than what Racing Beat made with factory bespoke 7.5:1 compression bridge ported, ICE water intercooled, twin turbocharged, open exhaust racing engines, on racing gasoline. (which set 244mph speed records in 1986, 238mph two way average).

There is no magic sauce in mechanical engineering (but WI comes close!), you make power by volumetric flow rates, mechanical and thermal efficiency. I run the std 9.0:1 compression ratio found in the 13B-REW, stock standard porting for intake and exhaust, and a small conventional type air to air intercooler (original SP rx7 item).

Water Injection is the only major secret?/magic? ingredient and a fine degree of tuning. Which allows what was only achievable on factory racing engines a few short years ago to now on stock standard parts, and a totally legal emissions engine........ unbelievable.

I class one of my biggest achievements is educating students and general public type people on the proven merits of Water Injection, and the power it can unleash while at the same time enhancing durability of your engine. If anyone needs any help feel free to read my thread or don't hesitate to ask Richard or other very experienced people who contribute here on how to get the same results we have all enjoyed over the years.

Great Stuff! Any vids of your car hitting the limiter in 5th then? :)
