Or a healthy modified 202.
what would be considered as good horsepower.
Thanks, John.

Will hopefully arrive in the next few days and I'll give it a test next weekend.
An estimate flywheel HP that I've calculated from my 1/4 mile times is about 240-260 FWHP.

82911 talks real dyno's not optimistic ones.
Cheers.

Does anyone know what a stock 72 XU1 is likely to get?
Just trying to gauge performance difference in relation to horsepower.
As Craig A knows, his car has a much quicker 1/4 time than a stock XU1.
Would be interested in the RWHP
John.

HP Calculator
In the calculator I use a weight of 2580 pounds, equivalent to 1170 kilograms = factory 1070kgs car + 100kgs allowance for driver & fluids.
Using the published 16.1 second 1/4 mile time for an LC XU1 the calculator indicates around 122 RWHP (factory published is 160HP FWHP).
LJ XU1 times can be inserted into the calculator and it will provide reasonably accurate estimates. If you use 14.9 seconds, RWHP comes up as 155 so matches what GTR-XU1 has said above.
Hope that helps.

I had my LJ XU1 tuned and dynoed back in 93. it made 150 rwhp but was a little lean up top so i fitted a holley blue electric pump. yes its got its factory JP and H252 head, carbs and dizzy however it did have extractors and 2.5 exhausta stock LJ XU1 makes 150-160RWHP

it started out with a 350 holley and then eventually went to VK EFI, it probably gained 5hp from the EFI but i reckon if you spent the time on the rollers you could get the same out of a carby setup ... maybe even more with webers or the like.

And of course he uses a good dyno, Bomber...everyone does...that's why no-one ever argues about horse power figures...much

Was that GTR the orange car that I drove?
It had the CDs.
Felt good. if it had 160 RWHP, I'd be happy with that.
It's always hard to tell by just driving them.

also has the l34 at only 80 kilo's heavier than the xu-1 with 260 kw's at the fly wheel.

Factory rates this car at 117FWKW's, G-TECH measured 87.7KW at the wheels. If you use the driveline loss calculation of around 25% then G-TECH reports 110kws, reasonably close to the factory spec.
Measured 400m time was 16.553 seconds, 0-100 times was 9.25 (NRMA tests 16.7/9.5).
I'll get the XU-1 out on the weekend and see what it comes up with.
John, happy to let you use it to measure your cars output, if you want to do this send me a P.M and we'll arrange something.

They got 307hp out of a 202 for a LJ race car. That is flywheel horsepower. And that motor cost lots and lots of $$$
I think they are building another at the moment, and they reckon they can flow the heads a little bit better and make over 310fwhp.
So if you have the cash. Anything is possible...

if thats to me heath. I'm pretty sure he said it was N/A with Triples. I can find out though if you want. It was for Group C racing i think. So it had to be like that i think.What kind of induction? I am guessing it's N/A EFI?

It would be nice to know the horsepower that equates to that happiness.
