I want more response..but a bit more power would be nice too!

[Dj ep]

will get back to ya tonight on that got to get back to work .

hi mate my bad it was just a crazy tdo4 hybrid . . i know how you feel with the flat spot of power . i have nothing below 2000 rpm but i think i have found a new turbo setup that will sort my problem . hoping to make around 250 bhp at the wheels making boost before 2000rpm and still pull hard to the red line . just got to save up cos my k26 kit is not selling ...

 

[artmull]

Haha, Nah!

NOS is cheating!

I'm going to stop bitching about the car, its fast enough for now. Probably just going to tinker about a bit with a few minor things.

Maybe heat wrap the manifold and downpipe, possibly get a PROPER stainless steel manifold made up in the future. Maybe go back for some map tweaks. I am still on stock limiter and have Pauter rods and Cruise valve springs..doh!

What rev limit would you guys suggest? I know gearing can help a lot in particular conditions and on the QTR mile.

You are using Pauter rods and forged pistons plus the PowerFC and using the stock limit?? You can move the limit to 8-8.5K RPM and the engine will still be reliable. You would need to re-tune re-map the engine to reflect the new rev limit. With your current setup if you change the final drive ratio from the stock 3.7 to 4.3 the car will accellerate a lot faster and perform better on the 1/4 mile but you will lose roughly 15mph from your current top speed.

Hi Artmul,

Yup, stock limiter!

Going to ask my mapper about a re-tune...
-
Without changing the final drive, assuming my turbo does not start to drop off at 8-8.5k what will the advantages be?

Or, even if the power does drop off, will I still acheive some gains?

What limit should I go for..8k or 8.5k!?

Dj,

No probs mate.

8.5k on stock crank, with no work done to it is a bit mental..! unless you have had some done?

 

[Gee]

It was machine/ground whatever when the engine was machined/forged?

Would 8k be OK then?

 

[turbo-fever]

yer my td04 setup is the same but if i get caught below bout 3000rpm then im screwed lol

 

[sx_turbo]

really its that shit?

i'm wondering if i done the right thing now

Would also like to know what rev limit would be ok.

You need to drive a TD04L Starlet with a proper tune mate before you decide to be honest.

Si_Glanza has gone from CT9, to hybrid CT9 to TD04L. Ask him if he would ever go back

Regardless of the setup, you will always want more. Unless you can get hold of a K24 setup, the TD04L is the best compromise for response/power.

Depends what you want from the car at the end of the day.

Cudnt have put it better, but once the turbo is in.... then the pull is alot powerful

@ GEE, yes 8.5K rev limit is safe on your engine.

Guys I post from experience. We have forged 5E'S here with stock cranks, the engine is balanced with aluminium flywheel, stock composite head gasket which was pushed to 30PSI (368whp) on VP C16 race fuel. If the stock crank could not take it then the engine would have exploded already. Boostjunkie's 5E made 320WHP at 26PSI on race fuel and he drives it everyday at 20PSI on 93 Octane pump gas and this car runs 12's in the 1/4. The only difference between the two engines was the 368WHP car was running WebCams while boostjunkie was using stock 5EFHE cams. Both cars use T3 turbos and if anyone needs the specs I can post them. Both cars use 4EFTE electronics plus eManage Ultimate. Boostjunkie is in the process of going stand alone ECU plus cams and shimless buckets. Some guys are scared run even 8.5:1 CR, yet there are 5EFHES here with standard internals and 9.8:1 CR making 290WHP on race fuel and daily driven at 17PSI on 93 Octane which is 230WHP.

 

[Gee]

Might go 8K just to be safe LOL.

Would love spec and pictures of these monsters you guys build Artmull.

 

[Aga]

i've had mine for 3 years on a rev limit of 8000, with no problems. been using cruise valvesprings too just to be safe, and the pistons are stock compression. only thing is, power so high won't be available without proper cams, even 256 ones. so, my revlimit was there just so i could keep on the gas while turning a corner, not for power. when drag racing, i used to change gears around 7200-7400...

(gotta dyno the new engine and see though)

Gee, theres no way to spool faster those turbos... only chance i guess would be a set of cams that work well in the midrange, like the 256's, but since i have no personal experience, i cannot be sure.

if it was lightened and balanced it will be fine

 

[GT_Ben]

Do you not read things, He's just said it was not lightend, just re-ground and balanced.

Please read Artmuls post above comeing from 'First Hand Experiance'.

Do you have any experiance in reving a 4efte above the standard limiter Fishy?

Ben

 

[Gee]

Just read the reciept for the work, it says:

Polish and race balance crankshaft, no mention of it being lightened.

Aga,

Was your lightened or not? I think a 8k limit could be useful in the scenario you have mentioned also.

Thanks for the info on the cams.

First step is just to try and achieve a minimal about of extra response just by doing simply things like heat wrapping etc.

Ps.

Would my intercooler piping diameter cause any sort of restriction?

lol, u guys in the uk really play everythin way too oversafe lol..

heat wrapping may get you a bit of response, keeping the exhaust gases nice and hot to the turbo could make an improvement, it does wonders for the engine bay aswell as it keeps it so much cooler! im suprised you didnt do it already

i guess when u get a taste of power ur greedy for more.
