Sounds awesome, My guess is a GTX35...

[Aggroman]

he just said GTX 3576

[WARLORD]

Ill try do a vid this week

[GTScotT]

Etsi bravo.

What are you revving it to, Nick?

[Lithium]

Very nice - is this on petrol? How is spool?

[WARLORD]

Etsi bravo. What are you revving it to, Nick?

8200rpm

any body know if a 32x32 map on the haltec would benefit with it only running 9x9 map less than a power fc im guessing not.but i maybe wrong.

[WARLORD]

yep its on 98 shell spool is nice and quick ill try find my camera and film it so you guys can see.

That's good power for 98.

I'm guessing its on full pelt about 5k? When does it start to get urgent?

[WARLORD]

full boost is in the high 3k 3600-3800 i don't know why it looks that way on the dyno sheet but its way earlier than 5k.

also for every ones interest my mod to the air box is real dam good dyno run with the box and without was the same,we took the filter out and ran it and put it back in and it was the same power.

so my gamble was 110% right.

Ah ok, thats interesting.

The dyno is indicating a powerband from 120-180kmh, so 1/3 of the rev range (roughly). If you were to do it basically 8200/3 = 2733, x 2 = 5466. So the sheet is saying its on power at 5500 if its revving to 8200.

Is it possible that graph is for a lighter ramp rate or something like that?

[WARLORD]

on the ecu maps its set a 9000rpm as i have just looked at the tune so i have NFI why or what id love to really tell you what i think at the moment its easier if i just pm you about things i also have haltech reviewing everything as we speak online.

[GTScotT]

Fair enough mate, you only need to discuss what your comfortable. Am just curious.

[WARLORD]

that's cool this road to getting a result has been a bit bumpy ill post a vid up so you can see how it runs.

[WARLORD]

yes you are correct 4820rpm full boost of 23 psi the build up is so fast that you could swear its much earlier its tuned in ve mode (volumetric efficiency tuned)which is new to me.

That's good power for 98. I'm guessing its on full pelt about 5k? When does it start to get urgent?

That's odd, its on fairly late. Yet if it feels like its on much earlier I'm guessing it actually has good pull before being on boost?

[NYTSKY]

Your setup is screaming for E85 Nick, that turbo is capable of making big numbers for its size.

I think 35R size turbos and bigger are wasted on setups that run moderately low boost levels. Chasing response is not really a goal anymore and you will only get frustrated doing so.

[Lithium]

Very nice power but I am so far fairly disappointed with the lag, feeling reasonable considering how late the turbo comes on is more of a credit to the rest of the setup in spite of as opposed to thanks to the turbo. Unless there is a setup issue responsible of course, that is definitely laggier than just would have expected!

[AngryRB]

i think its probably normal for a gtx of that size, my gtx3076 on 98 was a late turbo, 18psi at 4000rpm but probably 4400ish til the back tires broke free.

E85 and more boost helped alot, but would do on most turbo's anyway.

disappointed nar its not that bad it really doesn't feel laggy honestly has anyone else had there car tuned on ve cos ive been in cars with lag but this feels different it could be set up.in the top end you see the torque drop of it was explained to me that its cos of the cams need to be bigger tuning in volumetric efficiency calculates the amount of air that can flow throw the engine and cos the head is ported the cams are my restriction ..............true or not i have NFI..lol thats the only set up issue that i can think of

its hard to explain it does not feels as it looks or sounds buy the dyno or the full boost by 4800 i need to do a vid on the car

If the efficiency of the engine drops off your VE numbers will tend to flatten out and sometimes run backwards.

That torque curve says it all. Add some more boost if you have a decent controller with rpm correction at the point where the torque curve falls over (150km/h). Power will keep climbing and torque curve will stay flatter.
