Got dynoed the other day and found out that my power is not getting transmitted to my wheels properly. Dave at KDR hasn;t seen anything like it in his life. He said they think the washers on the stock differential probably gave out and the car won't make power. the turbos work great he said. It pulled 300 rwhp but now I have to dump more fukking money into the car just to get power out of it. He said it took twice as long for my car to reach 120 mph than other cars. Weirdest thing he's ever seen. I'm glad the the BNRs work great sequentially - he ran it up to 16 lbs but no hp - after 11 psi or so the power wasn't there like the clutch was slipping, but it wasn't. Any ideas? Anyways, I hate my freakin car and wanted everyone to know about it

 

i know how ya feel man. it is a patient game indeed.

 

Just curious what kind of gear lube do you use and if you ever changed it in the diff? how many miles do you have on it? I would get another diff from a wrecked car.

BTW what stage BNRs do you have? Good to hear they run good seq, I'm trying to decide between those and the 99s

 

Did he make sure they didnt have the brake patially applied on the dyno or that your E brake wanst partially up???

I mean even if you only made 300rwhp it wouldnt take all that long to get to 120mph. How do they know your clutch is working right? Did they feel it out on the street to confirm its not a dyno issue?

Damn man, I know how it feels man. I'm sorry to hear about your probs.

i think every ****** fd owner in the world knows how you feel.

 

Is there a way he can check that first? Are there other things he is going to check first? I hate to see him swap out the diff and that not be the problem cause I imagine its not exactly cheap.

STEPHEN

 

i feel you man... but when it runs..... it's the best!!!

 

i dont know man, check the flywheel and the clutch.

one of the two might be gone. my first guess would be the flywheel.

Here is something I found on another thread:

 

I think the single turbo gods put a curse on anyone trying to get a clean run on upgraded twins ...good luck with it, hope its something simple.

 

If you put down 300hp it shouldn't take twice as long to get to 120mph. HP is moving weight over time, if you had 300 hp then the time has got to be short.

Also if anything in the diff is going out there will be A LOT of heat there. Say if you should have put down 360rwhp then the diff would have "absorbed" 60hp. That adds up to a lot of heat really quickly, it won't last long doing that.

^^^ What he said ^^^

 

Speak for yourself, my man .

Sorry to hear it, Barry....something isn't right, obviously. If anyone can get to the bottom of it, Dave can. Are you running the dynamic seals on those BNRs?

 

Dave ran a FD on the dyno right after mine and pulled great numbers. Allthough it's a possibility, I really don't think he'd have the e-brake on. The differential fluid was changed 9K miles ago with Redline. The clutch and flywheel have around 6K miles on them. He said the turbos work perfectly. He ran them up to 16 psi but the numbers dissappeared after 10-11 psi. I wasn't there so don't really know what the hell's going on. He said the car did pull hard up to a certain point and then the mph kind of dropped off. I don't know but I can't put any more money into it. I was going to sell it this spring. I figure a FD with 380-400 rwhp with upgraded sequential twins should pull down $22K with everything on the car being basically new.

Here's my history with my ******* FD:

Bought the car in August 1998

For 2 years I drove around with a split lower IC hose and was only boosting 2-3 psi but didn't know it since I didn't have a boost gauge. Got that fixed.

April 2001 my coolant seals let go - time for a new engine - I add all bolt-ons with a streetport

August 2001 switched to non-seq - car was almost too laggy - found out my primary turbo had too much friction and car was missing about 50-60 hp

May 2002 get BNR twins from Bryan

August 2002 install BNR twins in the car only to find there is a cracked wastagate - car wouldn't boost past 10 psi even with closed wastegate - send turbos back to BNR too see what he can figure out

Now - install new BNR twins - turbos work great - discover a new problem which nobody in the freakin FD world has seen before.

I'm done with this car.

 

Kwik, sorry about your problems.

coincidence or not, how come EVERYONE with M2Twins or the BNR Twins that has dynoed has some weird problem and cant get any power?

I hope you get your problem fixed, I know how you feel.

 

since its a pile of crap, I'll take it off your hands for a 12 pack of bud light and a mickey mantle rookie baseball card

Wait, the mickey mantle is worth more nowadays.

That has got to be the weirdest story I've ever heard...lately.
So, recap from other posts etc.

Dyno before new BNR turbos yielded what HP ? dyno sheet available? Compared to now, which we know so far no dyno sheet yet. Only change is the turbos. Slipping clutch is eveident on the dyno sheet. Trying to think of other things, besides tuning the pfc.

I'll see that bid and raise you a Roger Maris!

 

don't give up.......... FD's are like dating a super model (from what I hear). Tons of drama....... but when everything is settled down it's love all over again......

 

What do you mean by too much friction Barry? Do you mean to say that a turbo can be boosting properly but be so inefficient due to frictional losses that it causes a HP drop? How would one know, say, if a set of rebuilt turbos had 'too much friction'?

 

batman, he's already resolved he was going to sell it long before, he was just trying to get it in great running order with some nice dyno numbers for the lucky guy who is going to buy it from him.

I'll throw in a Mark McGuire usa team rookie card that was worth hundreds a season or two ago, but has settled back down to the $10 range.

Barry, was the flatter door crack confirmed by Bryan? Just wondering since Bryan doesn't tend to let things out of his hands that are obvious. Maybe KD isn't doing something right, even though they have a great reputation, people can make mistakes.

Tim

 

Sorry to hear it.. I think 90% of FD owners get frustrated with the car at least once(and yes we know goodfella isn't included in this 90% lol). You've just been frustrated with it a couple times.

Your in a bad position because if it's that low on power it will be hard to drive home and even harder to get someone to buy in the spring. Not to mention it takes months in advance to get a car into KD so you probably won't have time to take it up there again for repairs before spring.

Hopefully maybe Dave will pull some low cost fix out of somewhere and be easy on your wallet. To bad KD doesn't have coupons or a frequent customer card...

 

this might be a possible scenerio.........

He fixes the rear end and then the car gets awesome HP numbers and then Barry decides not to sell it until the next event happens..........

 

Way more than once...

 

Agreed.

My car is going up for sale after the new motor too. If I don't get the right price I won't mind keeping it but if I do find a good buyer then I'm kicking that bitch out of the house! I'll get a corolla or something I'm sick of this bs.

My dad: "If it's not a piece of **** then why can't you move it from the driveway?"
Me: "Umm, yeah it sucks."

 

you would be able to tell pretty quick if it was the diff it would proble have snaped the shaft eatting that much power i would check the tranny has any one drove it on the road and checked for problems

if the dif was the case you would be able to tell at lower speeds and lower rps and bost

try taking off at really low rps and see what you feel and drive th car around the block and put your hand on the pumkin see what you feel
i donno if you are losing that much power it should not be hard to fiend

i hope it works out and good luck

i have had 5 t2s it my time i have had lotsa strnge **** go wrong but this beats all cept that one time i ended upside down in the ditch i think that was my fault
