[KRAMSNEHPETS]

Car now back with me after a long drive home in darkness and rain. Got to do a few miles in it, change oil circa 500 miles then a final dyno on 8th dec. Need alignment checking as back end feels very twitchy after having subframe off car. Looking forward to seeing what the end result is. Next day on 9th is day at snetterton in the other 2!

Could you do a write-up on your current spec on the engine?

[KRAMSNEHPETS]

Road car 2zz rotrex hit the dyno yesterday. got a bit hot when the fuelling was being done. got go look at why fuel supply trails off at at 7500... 199 torque. fly bhp works out to circa 325. was hoping to be a fair way above that like the celica boys are. hopefully it all happens in the last 1000 rpm.
90 mile drive home. all was well until I did a high speed 3rd gear run. have lost some power. stopped at petrol station to find engine lid jammed shut!!!!. thinking a hose has come off as I can here charger working or the cat has fallen to bits!. will try and look at during the week

[1979scotte]

Oh the joys of modified cars.
Hope its something simple.

[KRAMSNEHPETS]

Suspect its cat, look on the 2zz forum on facebook, put a video on there, whole exhaust was glowing red hot. car being looked tomorrow bymy local man to see what issue is after getting engine lid open , think he may have to remove exhaust to get to release!

[KRAMSNEHPETS]

cat had collapsed and engine release cable outer cover had melted.... Ct has now been gutted and performance now  back to normal, now got to find out why fuel supply trails off at 7500rpm

What fuel pump are you using and do you have a rising rate fpr?

Any updates on this build?

[KRAMSNEHPETS]

No news really. All OK and running fine, Have got to get a new rear silencer as the one is fitted is to loud. Will go back on rolling road after as last time the cat melted. May have been the issue why power was dropping away above 7000 rpm. Want to see it revving up to 8500 prodcing full power

[Dudi]

Have you got this running near it's redline yet?

Would be superb to get a review and some videos of it.

[KRAMSNEHPETS]

not yet. new exhaust silencer on 27th and on dyno 4th may to see what can be done

[KRAMSNEHPETS]

Went to visit Steve Norris today, Megallian Motor sport to have exhaust modified , to loud (orders from wife). Not gone exactly to plan, need to move battery from where it is now ( behind rear light) for exhaust to fit properly and found lamba sensor destroyed  where it has been rubbing against a sheild. so am now on way home on train ( expensive), will have to collect one night this week to get it to TDI at Thurrock  for the hub dyno session that it is booked in for at 9am next Sat. Had a bit of fun on the way up here, left and Audi S3 driver looking a bit surprised! All friendly, gave me a way when he left the motorway
So, if all goes to plan, relocated battery, new exhaust box, on dyno to get it to fuel beyond 7500 rpm, i hope with  revised BHP and torque numbers. Oh and have also got to get trackday car to headcase next weekend as well. good job its a bank holday next weekend!

[KRAMSNEHPETS]

Road car on hub dyno today at Torque developments international at Thurrock.Vey happy with results. Charge cooler is working  well at keeping temps down. Engine now revving up to 8200, lift comes in at 4000. Numbers are 319 at the wheels, allowing 12% lose, at fly wheel, 363, 286nm torque at 7000. Feels pretty quick! 
Was advised to look at sir filter size and location to improve air flow

[tomaky]

Good result.
