    1990 Talon Tsi English Racing build 2016

    ...John said “They're not bad for driving but you will still stall things out more often, and hill starting is a bit of a bi***. I basically overrev a bit and don't freak out about slipping the clutch at a higher rpm than other clutches.” I said “Yeah, starting uphill is where I have some...

    Strange rod bearing damage

    Even if you only make power to 7500-8000 with a 2.0 the extra 1,000+ rpms of overrev will help a ton on a road course, especially with how these transmissions shift.I would do exactly what you're doing for now. Check everything, race bearings, and run it.

    Pitbulls 99' GSX "Be Smart!" Build

    ...I had some fun with awd launches. One of my coworkers getting a surprise.Then it happened!I was racing a buddy in his 2010 ctsv and went to 2nd instead of 4th. Resulting in a nasty overrev that tapped a couple valves and I suspect was the cause of the toasted oil pump.That was April 2014

    Question about dsmlink

    Yeah that's what I thought in first place but if it's similar to Honda power shift as "dsmkauai" said which makes sense then shouldn't be that hard on tranny of course as long as you know how to shift and don't overrev the engine... Right? Correct me if I'm wrong

    11,600 rpm down shift!

    ...and make sure everything internally is ok. Im also having my default gear set to 3rd instead of 1st so if this happens again instead of the overrev it will just be a bad pass.I looked over the motor and the bottom end is trashed. The thrust bearing is worn believe it or not so I guess my...

    What did you do to your DSM today?

    ...clutch.if i'm not mistaken the clutch pedal should always be pressed alll the way correct? and when i accelerate, is it ok for the car to overrev a bit while trying to catch up the speed i'm inputing?I know thats a tech thing, but at least i replaced my clutch and cylinders :)Next...

    1990 shifter questions/problems

    ...going for a 3rd to 4th shift only to grab second because your shifter's got sloppy side to side play because that springs not working. Overrevving with the throttles one thing and can be controlled by the ecu via preset rev limit:7500 rpms. This, however, is NO defense against a MECHANICAL...

    1g eclipse rev limiter?

    ...like 'my1gdsm' said. I just want to know if my car has one or not cause if it doesnt I know someone that can hook me up with a MSD 6A ignition so I'll have overrev protection and I'll have 2step :))))). I just want protection. because if my car had more work to it I coulda easily ####ed my motor.

    piston to valve clearance

    ...Did the engine have a timing belt slip? Honestly, by looking at that, I'm wondering if the oversized valves hit the piston, just because they were oversized (due to the way Wiseco made their pistons and valve relief). Now it could be an overrev as well. Hard to tell without claying.MB

    Missed 2nd gear @ 7k rpm

    Scary thought! lolThe only thing that makes me feel better is that if in fact bolts were backed out, I would get a noise on a consistant basis. I drove to the bank and back and didn't notice any issues.I think it just scared me a bit.I think the rev limiter is at 7 or 7500 but it...

    Missed 2nd gear @ 7k rpm

    ...Under normal conditions the rev limiter keeps you from doing damage to the car.Edit: The sounds that your talking about could be due to a flywheel whose bolts have backed out. However, you need to really overrev the engine for that to happen. When you press it the clutch, does the engine...

    i owned a 1980, same model and everything. its actually a 2.0 slant 4 and you can overrev it to 8k and it wont blow! i tried when i did dirt trails with mine and it ran forever! make sure you use sythetic in the tranny and rear diff or it will cook itself...buy the damn thing and change the...

    First time back at the track...

    Yeah that about sums up what happened. I was hoping you wouldn't say that. I was thinking that the misshift would be mechanical due to the trans multiplying the out put based on the shorter gear. Tomorrow my buddies garage should be open and i'm going to limp it there carefully (about 1 mile)...
  14. Phil1320

    First time back at the track...

    ...rev limiter means nothing here at all, this is a mechanical over-rev situation. Many times the t-belt will jump in a mechanical overrev situation. It's a matter of how much and if it did is there is any internal damage. After inspecting, if you see the belt is off, time it to spec, fire...

    ...wable. New MHI turbo. . .MHI turbos last a while; but there's nothing like over revving them to blow them up. All turbos blow up when you overrev them. They blow up. It's just a fact of life. Really. Nevermind the raves and reviews. You actually CAN blow up a glorious MHI turbo ;) . All you...

  17. Whine, spinning clutch, knock while releasing clutch

    ...disengaged it stops. There's a whine as I step on the gas and if I give it too much gas the clutch slips. Brand new master cylinder and bled/calibrated so that's not the issue. I'm thinking transfer case or clutch, but leaning towards clutch given the overrev.Confirm my suspicions...

    * * Advised me for good choice for over 800hp

    Kevin, thank you for the clarification regarding my comments. I was given that information by some of my engine builders that deal with some really high-end Professional engines for marine, Nascar, and other NHRA racing bodies. This was when I contacted you concerning the Beehive Springs that...

    ...at the seat ID would open the valves with the head sitting off the car. Both of them work just fine. One has only about 1000rpm margin for overrev NA, yet works fine to this same rpm range turbocharged at over 35psi. That engine only has ~45lbs on the seat with a 34mm valve (it is not a...
  20. what do you think about this masterpower turbo

    sorry i couldent find any hx-52 that would bolt to my manifold for 825. i will get a better turbo after i go to a few races and the track is shut down. but for now i am running the masterpower turbo. and i am not intrested in buying a used turbo. you can buy all the used turbos you want. but...

    what do you think about this masterpower turbo

    ...new cars, the evo3 16g, greddy, 280 cams, and new real estate. The MP t76 will last forever within the flow of the p-trim. Once you start to overrev to compensate for the tiny turbine (which is huge to the rest of us), you'll be looking. And by the way, the superback tech, turbine wheel...

    Holset Turbos, PART 4

This makes a holset even more prepared to overrev and still survive, stretching range of operation even farther. Since the compressors are so efficient, you may actually get into the lower range...

    ...bearing i'd say, atleast it looks that way and its messed up the worst on both motors. I DID NOT shift from 3rd to second or anything and overrev the motor, and i did not beat the shit out of the second motor, or the first one. Like i said I dont know what happened, but if anything...

    Sure there is. It's fun. ;)

    evo 3 16g vs new fp 18g

    ...16g is completely tapped out at that point. This means lots of hot air to tune around and no pump gas. As I've mentioned, now more than ever (since the price is so affordable), there's no need to overrev a poor little evo3 16g, when you can use a properly sized bolt-on turbo for a 380-420 hp...

    evo 3 16g vs new fp 18g

    ...because the higher flowing turbine will yield more hp per psi than the evo3 16g at boost levels neccesary for 380-420 hp. There's no need to overrev a 16g turbo to do waht an 18g can do much easier. And this "new" td06 turbine wheel looks to spool very quick for it's flow. Which means great...

    TD06H 20G feedback...

    ...MORE!!!If you have an MHI unit, especially an MHI built unit such as a true 20g (no offense to FP); you can beat the crap out of it, overrev it, whatever. So this is why a td06h 20g is comparable to a 50-trim. It shouldn't flow more, but you can push it so that it just might on your setup...
  30. Which way to go 2.0 or 2.3?

    ...correctly. I spoke to both Buschur and AMS and they recommended max revs at or below 7500 RPM. Having just logged the car, I made max airflow at 7100 so there's no need for me to even go that high. As long as you don't overrev, the cylinder walls should weather the side loading forces rather...

    pulled sparkplugs and it was oily

    ...a few thousand miles to make sure everything has a chance to seat properly. Change your oil after 500 miles and then do the usuall 3,000 and you should be fine. If you high boost or overrev to soon you might be doing another engine again so I would play it on the safe side and take it easy...

    mechanical overrev, whos done it? what broke?

    I had my first one today. My tranny hates going into 4th after being shifted hard into 2nd and 3rd. So I banged it hard and bounced off into 2nd. Thankfully I was on the brakes at this point and only hit ~8400rpm (according to the SAFC). I quickly put the clutch back in before it was even...

    My Car Won't Stop Reving To The Max

    ...air has to be getting into the engine somehow, either through the throttle body directly or a leak in/around the manifold. The car won't overrev simply because the ECU thinks there is more air entering the engine than what actually is-- at least not to the extent you're seeing. I know you...

Lets say 45MPH, but at a throttle limit of 80% or higher, if I overrev the BC will toggle to low, and if I have excesive knock, it will switch to low boost. Being FWD this featuer is awesome and makes it a little...

    Turbo - what's a better buy?

    But you said you wanted a shep tranny to shift to 9K for fun. you didn't say anything about building for an accidental overrev.:confused: No biggie. IMHO, a shep or tre tranny becomes more and more a neccesity as you start progressing from the 350 whp point. This just my opinion. but being that...
