Can VP Nirtorace 50 be blended with VP-M5 to increase the nitro percentage from the 7% to say 10-!5%. I am using a hydrometer and a temp chart to measure the percentage.

Thanks

I am looking for your input on this.

Thanks

Well I did a little chemistry experiment this afternoon. I blended 500ml of M5 + 250ml of Nitrorace 50 and it yielded a blended specific gravity of .849 @ 57 degrees or about 15% nitro by weight.
The VP technical bulletin says the M5 specific gravity should be .816 @ 60 degrees or about 5%, my M5 specific gravity was .807 @ 61 degrees or about 4%. I was un able to test the Nitrorace 50 as my hydrometer is a .800 to .900 for a max of 30%.
I would have expected that if I had blended 500ml of M1 with 250ml of the Nitrorace 50 it would have yielded a blend of around 12%.

Now I am not sure if the 15% nitro by weight value is correct because of the combustion additives and top lube in the M5. Anyone want to comment on this value.
　
Thanks

It's the reason this all got started.

Then let me help you,, stick with M5. Once you start with nitro you will be tipping the bottle more and more.

Yea I have read that, just like adding more boost. MORE MORE MORE

Just looking to try 15% for the last T&T of the year, what the hell I all ready have it. May be I will buy 5 gallons of M1 and mix it together.

Thanks

I would just add some nitro to M5. Reason is the M5 has the lube plus some other goodies so you won't have to add a ton of timing.

Lmk how it works out please.

Here are my results. Nothing real steller but some gain. I would like to have tried a good 20% mix, but it just didn’t work out. Maybe next year.

Run # 1 M5 5% actual .115 pill
1.382 60' 4.094 330' 6.406 660' 106.18 mph 1598 da

Run #2 M5 5% actual .120 pill
1.387 60' 4.100 330' 6.417 660' 105.92 mph 1534 da

Run #3 blend??? .120 pill
1.403 60' 4.123 330' 6.440 660' 105.79 mph 1328 da

Run #4 Mix %?? .120 pill
1.385 60' 4.0912 330' 6.399 660' 106.61 mph 1201 da

Final run
Run #5
2gal M5 + 1gal NR50 + residuals = a 12% actual mix .120 pill
1.367 60' 4.065 330' 6.367 660' 106.62 mph 1196 da


All runs with 42 degrees timing at 10.5 - 1 CR

Sorry I didn't get back quick enough. Paul has a pretty dang good handle on the nitro and alcohol info. Personally I would just take the Nitro 50 and blend it down with M1 to get the ratio you want. It the old days, for every 5% nitro we put in alcohol, I recommended at 15% fuel increase. Once you get past 20% nitro though, the mix was harder to light and you may run into some issues.
