Thank you all . The numbers are indeed unexpectedly high
On the road, the turbo spool's much faster.
No it is not on E85 .We don't have the magic timing juice here in Greece(at least not available in gas stations).
I am using 100Ron shell V-power, the equivalent in the states is 93 pump if am not mistaken.
I am going to increase the rev. limiter from 7000 to 7300. No more because i love my motor and i want it to live for a long time.
Here's my timing table, all comments are welcome, am tuning the car myself.

My spark table is very similar in the 250kpa zone. I actual have more spark advance in the 200kpa/220kpa area. I get 360ish whp on the virtuadyno in dynojet mode but i'm nowhere near those numbers on the roller dyno.
Engine usually outputs maximum hp around 6800 if boost/spark advance are kept linear. I know 6258 is on the merge of loosing efficiency on that area and the 6758 is just picking up around that area and your virtuadyno just shows that teorical gain. Any 100-200kph figures?
Traction control in MS is very simplistic, only suitable for drag pulls i think.
Once again, congratz!

You have the upgraded valve springs, you can safely rev the engine to at least 7500-7600rpm. I would if I were you since the engine seems to be asking for it. I have my rev limiter set to 7450. I never take it that high because I have a 2560r that runs out of steam past 6500, but again you will be fine in the 7600rpm range.

Do you have a build thread i can read? Also can you share your spark map, so i can see how much more you are running?
I dont have any figures yet. I will have a dragy in my hands pretty soon
I know that it is very simple and i am going to use it, just to help me get off the line faster. I read somewhere in here, that a dude uses it in Auto X and it kinda works.
When i have time, i will sett it up and give an update.

I dont want to start the good old feud, Europe Vs American BHP Vs WHP Vs HP Vs KW.
I post the results, so people can get as much info as possible.
Car feels great and next time,(when i sort out the transmission "destruction" issue) it will be over 400 Bhp, Whp , Hp
#12
i was trying to know from the OP if it a known free HP dyno or not. As OP referred car must be amazing to drive and we’re trying to gather info.
PS: on your virtuadyno you put 2728 wet weight, have you weight the car?
#13
It’s not that. As I said, on a euro roller dyno you would never get that bump over dynojet wheel power. On Euro dynos you get crank power that equals manufacture numbers, and you remove drag calculated during dyno coast on deccel. As an example: a stock bp4w will measure 140hp crank and 105whp. This is equal to whp in a mustang dyno.

On VD that is not wet weight. It is the total weight of the car and the driver
And yes it is fat and heavy as a pig and i love it

I believe soviet went over 400 on pump gas
As for EGT, never. Because i have a trackspeed manifold which is cast stainless steel ( i love it!), i dont want to punch a hole on it and then weld a bung for a EGT probe in fear of it cracking. I will shoot myself if anything happens to it.

Thank you. Just a reminder, it's HP not WHP. .

Did soviet have a tubular manifold? I've not seen any cast manifold EFRs make near yours on pump though.
I understand not wanting to drill/weld that piece of art!

I didn't mean to imply you intentionally mislead anyone, just that most here will assume whp by default. I wasn't calling you out, just trying to let everyone else be aware of what's being presented.
I know when I post things here, I have to make an effort to convert units from metric (kw, cm, mm, km, L, nm, etc) into freedom units. It just helps everyone compare from an standard level.
The numbers are impressive, I bet it's blast to drive, I'm definitely a little jealous.
