Re: Rotary "Summer" Unit GB interest
 

We have decided ship free to US and Australia. Price will be as posted on the forum.

In USD:
HFS-3 + summer bundle 735 + 120 = 855 (non GB price = 735 + 299 + 85 shipping) = 1119.
HFS-6 + Summer bundle 945 +120 = 1065 (non GB price = 945 + 299 + 85 shipping) = 1329.

thanks Richard...free P&H..love you long time...;-) lol

Re: Rotary "Summer" Unit GB interest
 

Thank you! Richard, You're awesome.

Re: Rotary "Summer" Unit GB interest
 

Hi Richard,

I'm on the list for HFS-3 + Summer. I'm not sure if this is the right kit for my needs and if I should upgrade to the HFS-6 + Summer instead.

My setup:
2x1000cc primary, 4x1000cc secondary, 50/50 water to methanol, 15-20psi boost

All opinions will be greatly appreciated!

Welcome to the forum. We can do with more rotary members!

Re: Rotary "Summer" Unit GB interest
 

Richard,

I have been reading about AI all day. My set up is 850cc primaries and 1680cc secondaries. What would you recommend for my set up? Im interested in the GB, but would like more info as to my application.

Re: Rotary "Summer" Unit GB interest
 

Hi All,

I found out about this via a post on FB so am new here today.
I have a 1977 RX3 with a Series 6 13B pulsing under the bonnet, I think the injectors are standard but am running a large diesel turbo, dont ask me numbers but about 14psi boost and an Apexi FC. I would appreciate info on which unit would be better for me to purchase HSF3 or HSF6 aong with the summer.
I am keen to get in on the group order and thankful for any info that will help me make my final decision.

Keep the rubber on the road
Cheers
Darren

Re: Rotary "Summer" Unit GB interest
 

You can use either system, If you vary your boost a lot, the HFS-6 is more suitable as it has a manifold pressure compensation input channel. The system basically increases the meth flow in relationship to the manifold pressure.

The HFS-3 can also do this but it is pre-defined, 70% IDC and 30% manifold pressure.

If you are running below 15psi, it makes little difference, at least less significant between the two systems.

What boost are you running?

Re: Rotary "Summer" Unit GB interest
 

Hey there I'm new to the forum. Jeff at Howerton Engineering told me about this GB. am already running an HFS-3 and am interested in the summer. Is this going to be for the V3 version that will interface with the HFS user port I read about farther up?

Put me down for a summer and any harnesses needed to integrate it with the HFS-3.

Re: Rotary "Summer" Unit GB interest
 

The summer v3 will have a special H3-harness that plug straight into the H3. The wiring should be very simple. H6-harness will be supplied for those who order the H6/summer bundle.

In your case, I will supply a summer/H3-harness for you. There will be instructions with the summer.

The older summer v2 is quite complicated to wire up.

Re: Rotary "Summer" Unit GB interest
 

Im out im getting my Kit via MRT in aust

Re: Rotary "Summer" Unit GB interest
 

MRT and I will give your support either way. I think getting it from MRT will be sooner as you do not need the summer.

Richard

Re: Rotary "Summer" Unit GB interest
 

There will be special harness for HFS-3 and HFS-6. No more complicated wiring as the Version 2 (originally designed to interface with the older kit such as HFS1 and HFS-5).

It will be very straight forward.

Richard

Re: Rotary "Summer" Unit GB interest
 

Nah just found out they don't have stock yet so i might just get it from you Richard do you do paypal or credit card

Re: Rotary "Summer" Unit GB interest
 

Thanks Richard, that sounds great I am really interested in getting one of these.

Another question:
The summer is designed to work with different sized primary and secondary injectors and combine each injector IDC channel into a single summed IDC signal that the HFS uses to meter H20/CH4O delivery so that it is kept at a constant ratio to the vehicle's fuel delivery rate correct? How do you adjust the summer so that each IDC input from the two injector channels correctly correlates to the percentage each channel is contributing to total fuel delivery?

Thanks in advance

Re: Rotary "Summer" Unit GB interest
 

Hi Richard,

What is the time-line looking like for these kits? I'm planning my build around the delivery of parts.

In a previous post you said the advantage of the HFS-6 over the HFS-3 is when using 100% methanol or when varying boost often (>15lbs).

Did I read that correctly? I ask because I will never run 100% methanol and I'm still trying not to make the wrong decision between the 2 kits available. My boost levels will be between 15-20lbs.

Thanks again!!!

Re: Rotary "Summer" Unit GB interest
 

At last some one in UK!

Re: Rotary "Summer" Unit GB interest
 

Hi Richard hows the progress on the summer going?

Re: Rotary "Summer" Unit GB interest
 

I have decided to go for a complete design update to the version two. The version three to the HFS-3 and HFS-6 will be childs play. I am still working on it and still intending to meet the target date, end of Februay. I may over run a few days, but it is definately worth it.

Richard

Re: Rotary "Summer" Unit GB interest
 

Yippeeee!!!!!

Re: Rotary "Summer" Unit GB interest
 

My tuner suggested I wait for the summer if it's 2 weeks from now...
Hopefuly you get it made in time then Richard. Thanks again...

Re: Rotary "Summer" Unit GB interest
 

I'm in no hurry, take your time to do it right! April would fit my budget anyways.

Re: Rotary "Summer" Unit GB interest
 

Alright now that there is a date im fine was a bit confused with everything Also Richard im unsure if you got my last email as my work email server has been on off for the last two days now. but i will go with a blue gauge

and how are payments to be made? paypal? DD? creditcard?

Re: Rotary "Summer" Unit GB interest
 

Hi Richard

Could i change my oder to a HFS6 + summer please matey!

Thanks.

Re: Rotary "Summer" Unit GB interest
 

You can update the list yourself, just copy and paste or use "quote" and edit.

At this stage, you have all the time on the world to reconsider.

Re: Rotary "Summer" Unit GB interest
 

Take as much time as you need to make everything perfect Richard! I'll wait!

Re: Rotary "Summer" Unit GB interest
 

I will do so and keep my time table as well.

Re: Rotary "Summer" Unit GB interest
 

4 more to go... Yippie Ki-Yay,

@ Richard, mate i pm'd you :D

Re: Rotary "Summer" Unit GB interest
 

is it 4 more to go or 5 more since im not getting the summer unit ?

Re: Rotary "Summer" Unit GB interest
 

I thought the summer's were discontinued when I purchased the last one over a year ago. Good to see they are back but I only need the water injection kit. Can I still get a group buy discount? I think I want the HFS6 but I can't remember the differences. It's been too long.

Re: Rotary "Summer" Unit GB interest
 

GORACER you should be able to as that is what im getting i believe :D

Re: Rotary "Summer" Unit GB interest
 

Ok, please add :arrow: GoRacer to list
HF-6 (only) :cool:

Re: Rotary "Summer" Unit GB interest
 

Go racer,

I will update your summer to v3 if you send the old one back to me. No hurry.

Richard

Re: Rotary "Summer" Unit GB interest
 

Oh wow, I didn't even know there was a new version. Thank you! :mrgreen:

Re: Rotary "Summer" Unit GB interest
 

The last summer module (v2) was designed to work with the HFS-5 (now discontinued).

Since you are purchasing the H3 or H6, it is only most logical way to move forward. With a direct exchange (at no cost), you will have the latest and I have a spare v2 summer for those with an older system who needs a replacement.

It was silly of me selling the last few.

Richard
