So, there are good rotary mechanics in Europe...welwelwel...where we can find your "pip"? website/e-mail/address/etc.

Speedworks

I'm right behind you Werny ;-) (nono.. don't get any nasty thoughts,eikeuhbah)

oh boy, this is getting nasty...

Sorry for the late response, i'm on holiday now.
You guys never heard of Pip Garner of WGT in the UK?

Here's more info http://www.wgtautodevelopments.co.uk/

Speedworks

Hehehe...I was just kidding.. keeping up the positive spirit :-)




Yeah I know WGT, they advertise on the Mazdarotary forum in the UK. Din't know it had anything to do with that. I should look into it.
Thanks for the tip

Dan Norton

Hi my names dan and live in the uk.....there was only one place i was going to take my fd3 when the engine lunched itself, was indeed wgtautodevelopments.

PIP rebuilt it all (everything was damaged, rotors, crank, housings, casings....the lot), street ported, 3mm apex seals, and installed my t78 turbo kit, intercooler, 1600cc secondaries etc etc etc....

Anybody with pictures on the Rally (?) RX-7 of Boonen/Boomen/Boom?
He was running/winning a few years ago...

werny

Oef, now I was getting scared for a moment or 2...

Speedworks

a pic from the 24 hours of Zolder. The Van Herck Race RX7 kept going untill just past 11 Sunday morning (started the day before at 5 pm) due to gearbox problems. As far as I know the car ran pretty much trouble free dispite a broken axle at Saturday evening after one of the drivers pulled out the pits in 2nd gear and twisting the axle. A few laps later it broke and had to be replaced.

The car was set at approx. 380hp after they took it to WGT in the UK to have the engine management reviewed.

I talked to Werner Van Herck, co owner and driver of the 7, who was pretty happy with the performance of the car but clearly stated that after blowing 8 engines this year they hoped to be on the good track and to put some extra time in other finetuning (suspension etc) for 2006.

Here's a nice pic of the 7 at Saturday evening. I can assure you that the flame is quite "small" compared to what I saw it doing...at about every turn on the track.
Let's say the fuel system is still somewhat on the ...."rich" side ..LOL

Enjoy

Beautiful!!! Yep, that's a small flame. Most lasted about the whole corner and were bigger Actually, the Van Herck RX-7 could be reconized by this feature the entire night. No other car spit flames anywhere like it! We were able to read the sponsorstickers on the side just because of the light created by the flames!!!

Any more pics, BTW? Mine are non-digital, so I'll have to wait for them.

werny

more flames...

OC94Rx7

Man, those are some great photo's. I REALLY like the way this FD looks...beautiful!!
Again, happy to hear the motor worked well this time and look forward to future race stories in 2006. Any chance you could get them to come on the forum for more details about the FD / races details??

werny

we could try to ask them...

Van Herck = Mazda Dealer - Turnhout - Belgium?

Speedworks

Yes they are the ones from Turnhout but TOTAL internet noobs if you ask me.

When i was at Zolder I talked to Werner and explained him about my PFC (regarding their tuning issues) and he was totally surprised I got an CU with direct monitoring. I also asked Jan (mechanic) several times to visit the RX7 forum even if it was only to follo certain discussions. They seem not to, which is a pitty with al the info on this board.

I will visit them in the following weeks because they will have a part made for me and to show them the PFC (Their Halltech doesn't allow in car monitoring while hte PFC can show up to 8 sensors at thesame time.

If there is some time I'll make notes(pictures) of what is on and in the car.

One thing that come to my attention was that at Zolder, the first left after the straight the car was pretty much bouncing in the back. I have no idea what suspension Pettit was running but there is some room for improvement.
On top I was looking for info on FD suspensions and found that the Aragosta suspensions seem to be top of the bill (and price, lol). Even..xtra research learned that Aragosta is...a belgian company :-D (totally wicked)

maybe a recommandation to Van Herck could be usefull for the future...

Greetz,

Ok, That's a shame they don't want to visit the forum. I can understand they might want to do there own thing, but with all those blown motors. You would think they would give it a chance. I know many people on this forum with far more tuning talant than me (single turbo), would be glad to help them out. We all want them to do well..thats for sure!

I don't know how much time they had to set up the car. Sometime you just don't have time to get it all right. I'm sure they have been spending most of there quailty time messing / tuning the motor and getting the setup just right was second on the list?? I don't know.... these are the things I would love to hear from them.

Look forward to your notes/photo's. I have always wonder what Pettit's race car used even thou I walked past it a few years ago in Florida....Candy took me for a tur of the shop and didn't have time to look closer at the race car.

werny

Yes please do, and don't forget the peoples arround the car: drivers/meccanos/pitgirls, etc.

Speedworks

I"ll sure do Werner.. especially the "pitspoezen" ;-)


Regarding the engine and when I had a look at it in their box (training day 6hours of Zodler) they are running some sort of T04 turbo.

Looking at the latest progresses in 3rd gen turbo world they should be switching to GT40 or R85 kit to reach for the 500Hp+ barrier as they want to do next year.
They will get ball bearing turbo and Oil/water cooled which the 'old school' T04 are not.

I"ll try to push them towards t he forum again.; although last time I even forwarded a direct link.

We'll see

rotary emotions

Well, maybe they just don't have the time to look through the piles of threads overhere?
I mean, they have a company to run, don't they? It also doesn't seem that easy to me to solve their problems overhere. You'd need proffesionals for that.
It's probable a budget thing too. I'm already wondering about a Mazda-dealer running such a car. This sure is a different baby then the MX-5 they used to race.
Nevertheless, I hope they will improve on the car, as it seems to have loads of potential still in it. Comparing their fastest laps with the fastest of the other GTB's, there wasn't that much difference, and they clearly said the FD wasn't fully developed yet. The main problem was that the others would run way more of those fast laps, while the FD was going up and down a bit too much.
Also keep in mind the engine itself isn't very developed at all: they claim to use an almost stock engine! According to Werner Van Herck even the seals on this one were stock! So I guess with a newer turbo and bigger porting, aswell as stronger seals, some more is possible.

Speedworks

the seal issue has been discussed many times on this forum. I don't think that there is much difference in power or durability between 2mm or 3mm seals.

A more important issue is indeed the porting. Obviously they don't have a clue on what they are running. I'm not that convinced that they are running 380Hp on a stock port/single turbo/Halltech and some fuel bits and pieces.

I told Werner i have a diagram with porting possibilities and related timing adjustments.
http://www.rotaryengineillustrated.com/re101/ports.php
Which could really help them out setting ignition right.

I guess they should go for a big streetport or small bridge and an up to date turbo to get optimal performance from this car.(Considering the short and cornery tracks they are doing over here, except for Franchorchamps)

And they should do something about the rear spoiler... it's just 4 bars wacked through the rear hatch with some sort of glassfiber plate over it... every time they need to be in the trunk (fuelsystem) they need to unplug the spoiler, get it of, get hatch off etc...

OC94Rx7

The motor in the car comes from Pettit racing right? I find it strange if it wasn't ported??

Looking closer at the car I can see what you are talking about. They should just cut the piece between the bars and re-attach it to the body (or make a new piece to fill the space), then they could just slide it out.

Speedworks

the first 2 or 3 engines were from Pettit yes. But after that someone local rebuild the engines (I know who) but they failed again. Even though I know from the source that they used all new materials in the engine. Obviously that wasn't the issue.

The spoiler thing is indeed hard to see from a distance. You would get my point if you would see it upclose. I guess it's functional.. but not optimal. (sort of speak)

rotary emotions

Well, the thing with the seals is simple: with a perfect engine, it won't really matter if there are 2 or 3mm seals: it will last. With a badly detonating engine it won't matter either: it will blow. But the extra "meat" on the larger seals might make the engine a bit more resistant to occasional minor problems.
As for the porting: 380rwhp (425hp on the engine) seems a bit much on stock ports, but it seems so strange that they wouldn't know what they are running at all???

Speedworks

Jep you're right... 3mm's will only help delay the point where the seals break and give you some extra breathing space when tuning. If the setting is wrong they'll break nevertheless.

Probably this Pip guy has enough rotary experience to have improved the ignition timing by "feel" to make it run a lot better.

As I understood from Werner Pip will be building their engine for next season; let's hope that will bring better results. Although i have a UK friend who had his engine fixed there and had an oil leak on the way back home just because an oil line wasn't tightened.

well.. nobody is perfect I guess

rotary emotions

That can happen to anyone, can't it? Kinda stupid, of course. I had the same once, but at least I didn't charge myself any money for fixing it
