Rx7 Holds Unlimited Rwd Record At Buttonwillow
 

Just to let everyone know Twins Turbo RX7 driven by Jack Mardikian ran a 1.48.3 and came in second overall only to be beaten by the HKS carbon EVO. This was at the super street time attack finals. Here are a few pic's. Eric from Twins Turbo will fill in the details for everyone later.

Badass rotary ftw!

this rotary is better then a blumpkin.

I know the guys from GST, they were there. That is SCREAMING!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Thats an awesome car. What did the HKS Evo run?

I was there.. The sounds of Un muffler rotary always evil ;) . Great job !!. Ithink they can do better . they only run two session due some machine trouble .

The HKS EVO. Run.............. !:43.xx

That evo is fucking clean.

And props to that FD owner who still rocks the retractable headlights.

Probably because he never use them.

thanks for the kind words guys..here is an on board video of the record setting lap..we defiantly have more left in her, we were on mid boost, lots of little things we will be addressing for next season..next season its on.

great work, guys. glad to see you're still doing your thing - and not only JZA80s, too. :)

Yes, I've seen this FD at a lot of NASA events this year. When it's up and running well it's really fast. Nice crew too.

Sick lap. Loved that catch at the crest of the hill when the car went airborne. :)

considering that nob taniguchi is the driver of the evo you guys did a great job.

Damn that engine bay is no nonsense just the way I like it. Great car and good luck next year.

Next time I remember to bring earpluggs!!!

congrats!

How much does the car weigh? Are you really using Tokicos? The car looks quick even if starts looking a little unstuck later in the lap (are those A compound Hoosiers)?

I don't know if you can read the sticker we put on the bumper " Headache courtesy of Twins Turbo Motorsports"...it reads true.

By far the loudest car we have ever built..one of the baddest also..

Nicely done. For a second there I thought it was an updated rotaryracing and reliablility car...well maybe it is :) Just saw Jack was driving it.

Any comments on how well the chassis is compared to other cars your raced in similar configurations?

Tim

wow that was a bad ass run!! buttonwillow looks like a pretty good drift track

Def not an updated RRR car..we took her down to the white meat. we started with a block. every nut and bolt, weld, wire, custom coolers, plumbing, fabricate everything, dyno ect..everything is Twins Turbo now. Not that i'm proud of her, LOL..
we have some pictures of the build on our site www.twinsturbo.com in the project car section.

:mspank: :clit: :drool1: :jerkit: :scared:

i hope i dont get in your way when i go down to buttonwillow...ill be a spectator for the moment

Congrats Eric with the second place. Great looking FD, I can see you have put a lot of time and work in that car. Best of luck

MM... how come the driver dont Heel&Toe ?

The Steering input.. is a bit weird on the cornerentery....

Awsome Brake !!
Just find out you guys have 4.77 final drive. was this set up used in Time attack ?

great lap!! congratulations. you use motul oil? i see stickers on your car. what motul oil do you use?

Great job Eric, I didn't even realize you guys had a rotary. Just the other night I read the story on you and your brother in the magazine that came out this month (can't remember which one), the Q&A you guys did. Very interesting, you guys do great work. I love this car. Also, where can I get one of those hoods? Haha. Would you guys be willing to make a few more of those and/or "mass produce" them? I'll be running a V-mount as well and a while back some of us on the forum had a deal worked out to get them made but it fell through and I'm still looking for one somewhere. Anyway, great job, good luck to you, your brother, and your company as a whole. Go out there and take that record for first place, I know you can, haha. Eric

Looks like top-notch work. I'm especially impressed by the wiring, labeling of connectors and hoses, and well-planned ducting.


By the way, there's a photo on the website that seems to be a vacuum distribution manifold; is that for packaging or is there a performance benefit to tapping all the vacuum lines into the same place?

-s-

PS, I was told that a fast RX-7 caught fire at the time attack last week. I hope it wasn't this one.

I was wondering the same things after watching the guy drive. ??????

-M

don't push it man... i've seen my share of rotaries but nothin beats a good blumpkin first thing in the morning especially after a good dream when u really gotta go.

somebody please answer my quetion about motul oil. does motul have oil for rotary?

wow... for a second there i thought it was a twin turbo... (twins turbo motorsports)

so how come its really loud sometimes and not others? wastegate vented to atmosphere?

We use Motul 300V 15-50
we also use the RBF600 brake fluid.

Scotty, as for the vacuum block we like to have everything where we can get at it in case of a problem. we also had a big problem with all of the vacuum ports on the intake manifold. nothing but headaches waiting to happen. we try to eliminate all "hoses" and use A/N fittings. the details are what will take you out on race day.
Thanks for the comments guys.
and jack drives the wheels off that car..i don't want to start any s**t but its not that easy to do..its easy to comment on driving style, the lap record was on this lap..fast is fast period....

thanks. what motul oil do you recommend for street and autoX use with lightly modified RX7?

Great Drive
 

Driving style is just that a style, there is no real right way on the limit. For example look at some old in-car or out of car video of Nigel Mansell. He squared off almost every corner and wrestled the car down to the apex. Schumacher is exactly the opposite. He almost finesses the car to the apex and wrestles it out.

I have been racing cars since 1982 and have done just what Jack is doing many, many times. I think that he is trying to preload the outside tire on initial corner entry and feeling for the slip angle before he goes full into the corner. I do this many times when the track is dusty or dirty or I am unsure as to how much grip I have and I still must go fast (like qualifying on a dirty street course on Friday). When using R compound street tires, slip angles are very important as it is easy to cook the outside front tire when you have a corner entry push or understeer, like I think this car has. TONS of power over steer though, LOL.

From my point of view, Jack is basically dealing with a slight push, unsure of the level of grip and the need to go really really freakin fast and minimize the chance of balling up the car. I think he did a great job, though slightly unorthidox on the corner entry steering input. I say more power to him.

Way to go and I am stunned at how fast he went on street legal tires. WOW!!!!

You guys are right. That is why they call it "driving style"

I've seen the car at SevenStock a number of times. Very well put together car.

What does it weigh wet without driver? And with driver?

Congrats on the fast lap times. The driver has skills for sure.

Exceptional work!! Especially considering the the sinister competition out there. Definitely great Boostin!!! :icon_tup: :icon_tup: :icon_tup: :icon_tup: :icon_tup:

:icon_tup: :icon_tup:

VERY WELL PUT! :icon_tup:

Awesome job, Congrats.

Congrats on the car, I found the video on youtube then earlier today I talked to Danny about it. Beautiful FD, keep it up!

Completely random that I met you at a 240 meet last night Chris.

Thanks for the complitments.

it was done on race slicks not street tires, he runs the unlimited RWD class

Tires were Hoosiers.

when did you guys start sponsoring jack? That was a RR&R car for a long time. I still see a rrr sticker! Glad to see he got away from XS!

congrats, that is awesome.

We don't sponsor Jack, He approached us after watching Steven's Supra that we build evolve over a few seasons..he was driving in the Grand Am series for GM (cobalt) and began wondering why his personal car (his baby) doesn't look or stay together like a REAL race car...we took all of the street car junk, along with everything else off of her and rebuilt her completely. RRR provided us with an engine for mock up. I'm not sure who is doing the engines next season being we had a few problems with the engine program towards the end of the season.

And GNX7, I wish you would have had the chance to see the car at seven stock. we didn't have the time to bring her this year. If you thought that the car was well put together when you saw it last, i would REALLY like to see what you think of her since we rebuilt it. there is not a thing left over from what you saw..
Eric

Maybe I missed it, could you mention what turbo that is?

Thanks
BigAl...

Would you mind letting me know what the specs on your tires and CCW's are?

lol, popped rotary says what?

;)

j/k

thats insane fast, mad props to those builders!
