I ran sh*tty times because of wheel hop and spinning. Next year I'll use my M&H's. I am going to try a set of coilovers because from what I hear it seems they greatly reduce wheel hop with street tires..... If that doesn't work then I'll try to fabricate an adjustable pinion snubber.


John

Rich- Thanks for the offer- I already have a set.

Hey John,
Forgot to ask how do you like the "Hollywood treatment"? Tried it yet?

I was just looking at some old threads and I found this quote from Matty:
https://www.rx7club.com/forum/showth...7&page=5&pp=15

"I want to upgrade my turboes soon. i am torn on what to do...here is where i am at and my thinking:

"stock twins....i dont think its a freak...people who have upped the boost to the 17 and 18 range on the stock twins have reported damn low ET's, 120 plus traps and very high 300s rwhp. It also seems to me that these people also know a crap load about tuning. I think its pretty obvious that there is a correlation there. "



What gives?

No- Not yet, however when I do I dont think I'll be able to keep the ladies away from me and my new chiclets!

>>from what i understand boostn7 has hours and hours of data logging in, tons iof runs, and modified stock twins to get his times.<<

Hours of datalogging and 1/4 miles runs....YES, tons

"modified stock twins" ....Wow, now my twins were modified!!!!!

The twins turbos were completely stock 94 FD twins.....no upgraded wheels.
They were converted to "NON-SEQ" the proper way.....remove all un-necessary parts!!!!

Like Kevin mentioned.....
With the right bolts-ons the stock twins should hit 118-120mph on pump gas.

With stock motor/intercooler I ran 115-116mph @ ~15psi
With the Greddy 3-row FMI it ran 118-119mph @ 15-16psi I put down 402 rwh(actual) on a dynojet on pump gas hitting ~18psi.......later running 120-122mph at that boost level.

Stock turbos (port-matched/NON_SEQ) eventually ran 125mph on a ported motor @ 18-19psi on pump gas.
Same night, I broke the shaft on the front turbo on the way home running ~20psi !!!!
If anyone took those turbos to the limit....I DID :-)

Car has always been about the same weight.......2910-2925 w/myself depending amount of gas.

matty

we went off topic...i am talking completely stopck turbos. and i was also meaning around 15psi..not many people run 18-19 psi for concerns of ruining the turboes.

matty

17 - 18 psi ruins turbos. i dont care to ruin mine cause i want to upgrade.

u really arent understanding what i am saying. it isnt that difficult, 120 plus traps are posible, but not norm. and people that do run this trap are breaking ****, have tons of track time, and are probably running an aggressive tune. These people arent your avg. Evidence of this is that they are remebered after 8 yrs for their accomplishments.
The original debate stemmed from the guy that said he will run 124mpg traps with 356 whp. with 356 rwhp and a guy that doesnt seem to have hours and hours of tunning , hours and hours of track experience, and not running on the ragged edge (14-15psi) aint gonna trap 120 mph. Yes some guys have done it but like i keep saying,,these are guys that work their *** off to get there.

rotorsownyou7

It isn't 356! It is more like 380!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!

Hahaha...Try at least ~400rwh to trap anywhere near 124mph in a 2900lb FD w/driver.

With ~350rwh you will run somewhere in the 116-118mph range...about 14-15psi.

Oh yeah- that reminds me, I broke a shaft too at the same boost and the same setup. LOL talk about a CLOUD OF SMOKE. Traffic stopped on the freeway. No one could see. Then I had to fish it out of my midpipe. It was stuck in the borla muffler. Ahhh, the good old days....
reminiscing...

You keep changing your story. First it was no car with twins will trap 120 mph or higher, you need a single.

"stock tweins dont trap 120.."

"stock tinw car traps 114-118mph"

"i dont see many traps better then 115-118 mph, if they are great its cause they are single"


Then I showed you one. That wasn't enough so I showed two, then three then a bunch of people here said they had trapped 120 or higher.

You said 120 traps aren't possible so I gave you multiple examples. I showed it takes ~360 rwhp on twins with a well driven and tuned car to do it. Not many have done it? If one person does it it is POSSIBLE. It's not the norm? BS it is, see below.

Jimlab
"I trapped 119.2 mph @ 14 psi. Do a little weight trimming and raise your boost up to 15+ psi, and I think 120+ mph is relatively easily attainable. Brooks Weisblat trapped 120+ mph, Kevin Wyum trapped 120+ mph, etc."

Kevin Wyum
"With the same bolt-on's done and assuming everything else is working with the car I could get 120mph out of any normal 3rd Gen, excluding automagics of course."

"Well then I hit 125mph on non-seq worked stock turbos. I thought you meant stock turbos. The other guy who ran a ten did it on actual stock turbos I believe."

Jodney
"In March of 2001 I trapped 122 mph at 18-19 pounds of boost with stock twins/stock port/m2 medium/ rp fuel pump/ crane hi 6/ PFC and m2 intake."

"I set up my buddies car with a similar homemade map. He has almost the same combo but a ported engine. Recently he hit 123 mph @ 15.5 pounds of boost."


Boostn7
"The twins turbos were completely stock 94 FD twins.....no upgraded wheels."
*Ported-motor/stock twins/pump gas*
-10.98 @ 122.9mph(ET streets)
-11.08 @ 125.3mph ( Nitto drags)

Anthonys 1993 Rx7 - 386 RWHP - 11.1@122.6 mph - Stock Pettit Ecu

This guy ran 120.6 mph on 360 rwhp on a 80 degree Florida day.

Now it's BONE stock twins and you can't exceed 15 psi?

Then you start in by these cars have extensive tuning...blah, blah, blah
2780 lbs plus driver gets you 120 mph see time slip, end of discussion.
Then it's the driver has to have extesive track etc. We are talking about the CAR, hp, weight and 120 mph slips not whether the driver is John Force.

Yellow R-1 with a SLIPPING CLUTCH and only 14 psi with heat soak made 356 rwhp and his car weighs LESS than the car that trapped 121 mph. Yellow R-1 has a better power to weight ratio with a slipping clutch! What part of that aren't you getting? He can turn the boost up and get another 20 rwhp EASILY not to mention his rich 10:6 A/F ratio.

Look, you were wrong, got shown you were wrong by MULTIPLE forum members with dynos and timeslips. Give it up and admit you were wrong like an adult.



It is all about hp/weight we are talking about the CAR.

Mr rx-7 tt

iTrader: (5)

Actually 356 rwhp would be enough.

Brooks car which went 121 mph in the 1/4.
2780 lbs /362 rwhp =7.67

Yellow R-1's car with a slipping clutch at 14 psi.
2620 lbs /356 rwhp =7.35

Yellow R-1's car has a better power to weight. We won't mention he can turn up the boost, the fixed clutch, etc.

matty

right. but it is 356 thats what dyno said.

Mr rx-7 tt

iTrader: (5)

Yellow R-1 made 356 rwhp with a SLIPPING CLUTCH. They also tuned the car to a 10:6 A/F with heat soak at only 14 psi. The car easily makes more than 356 rwhp.
Secondly, Brooks ran 121 mph with 362 rwhp in a car that weighed 160 lbs more.


Lastly,
This is what Yellow R-1 said
"From what I can tell, my car is likely a mid-to-high 11 sec car (maybe traps 123/124 or so?) Pure GUESSTIMATE"

It was an off the cuff statement. Then Matty came in with no car on twins will trap 120 mph plus.

Mr rx-7 tt

iTrader: (5)

Yes at 14 psi with a slipping clutch. Clutch fixed, more boost, not heat soaked...want to bet it won't dyno more?

matty

it is hp weight i agree. he made 356 and weith driver is around 2900..go do the math.

honestly i would admit i was wrong but i really dont think i am. it isnt the norm. i will concede that some have done it obviouslt. but it is very rare. so rare that if someone was to aske me what a stock turboed car runs when modded i would say 115-118mph cause that is the norm. I made 340 rwhp but trap 116mph on a good run. those numebrs works..go use a calculator mister physics.

Mr rx-7 tt

iTrader: (5)

Did you read the info or are you having problems with reading comprehension? One more time.

Actually 356 rwhp would be enough.

Brooks car which went 121 mph in the 1/4.
2780 lbs /362 rwhp =7.67

Yellow R-1's car with a slipping clutch at 14 psi.
2620 lbs /356 rwhp =7.35

Yellow R-1's car has a better power to weight.

having been professionally trained to drive, courtesy of the us military, i dont feel the need to prove anything.

we'll just see what happens when im up to bat at the strip.... and if i run a slow time there.... then i run a slow time.....

matty

yes i saw that....

Mr rx-7 tt

iTrader: (5)

I did, with him in the car it's 2790. He doesn't weigh 280 lbs.

No you are wrong! Period. There are PLENTY of cars that have run those times, see the LIST. All it would take is ONE car to do and you would have been wrong anyhow.


So beacuse you can trap 116 with less power that's all that matters? I don't need a calcualator even though the numbers agree we can just read the actual facts and results! They are called time slips and dynos from the 120 mph runs! You lose, debate over.

matty

check out time slip section...much lower traps in there then the five u have accumulated over a 10 yr span. I wont attack your intelligence but it seems to me you dont know thje difference between what is normal and what is EXTRAordinary.

Mr rx-7 tt

iTrader: (5)

No, I don't think you understand.
You have decided unless it is posted in a ceratin area they don't count. What you don't seem to understand is it only takes ONE to prove the fact. We have MULTIPLE traps above 120 mph. Secondly, there are not that many RX-7's with those certain mods we are discussing. They all have to have ceratin mods, tuned, and DRAG RACED. How many cars fit those specs?
Bottom line, 360 rwhp gets you 120 mph traps. That is not debatable and is FACT.
Lastly, I wouldn't suggest you and try an insult anyones intellegence especially with your great spelling.

matty

i am done arguing you simply dont understand....have u ever taken a statistics class? you would benefit greatly. i am not attacking you in asking that. You seem to not understand that when u have a data set there will be deviations. You exclude those as they really dobnt represent the larger group and therefore are anomalies. in 10 yrs time u will ahve a few cars that did something way above normal. You really shouldnt inlcude those in developing a thesis.
For example...yes i agree with you that the stockers can make 400 rwhp. But that is by no means what you can expect from a full bolt on car. Of the 1000 full bolt on cars in this forum...we could probbaly identify 5 cars (if that) that made 400 rwhp. That isnt the norm and way out of the bell curve. There fore if someone asks me what the stockers make i would say 340-365 rwhp...cause thats is what the other 995 cars make. Get it?
i will not be responding any further as u simply dont udnerstand..u must not have the capacity...its fine.

i dont have a spelling problem i have a typing proble...i work on a stock trading floor and frankly dont have the time to proof read, dont ask me how i am gettign away with typing and responding so much.

maybe next time we can meet at kd rotarywhen i ask him to tune my stock twin car to 400 rwhp so i can trap 125 mph.

rotorsownyou7

He said his car weighs like 2800 w/driver and he is pushing 380.
